Gambusia marshi (Minckley & Craddock, 1962)

Etymology:
Gambusia: derived from the Cuban term Gambusino, which means “nothing”
marshi: named in honour of E. G. Marsh, Jr,

First description:
Minckley, W.L. 1962: Two new species of fishes of the genus Gambusia (Poeciliidae) from northeastern Mexico. Copeia 1962

Common name:
Robust gambusia

History:
Collected by Minckley, Craddock, Donald R. Tindall, and Charles B. Stone on 16 August 1960

Group:
Panuco species group comprising of G. marshi, G. Panuco, G. regain,

Type Locality:
Río Salado de los Nadadores, near junction with Río Salado de Monclova, 1mile south of
Hermanas, Coahuila, Mexico

Distribution:
Cuatro Cienegas basin and the Río Salado drainage, Coahuila, Mexico

Habitat:
Gambusia marshi is generally found in slow moving waters, regarded as most adaptable fish that can live in most environments, it can be found in most types of habitat from natural streams, marshes and lakes to artificial canals.

Size:
Males 3.5cm, Females 6cm

Distinguishing Characteristics:
Gambusia marshi has a narrow but deep body, this is more noticeable in the male than the female who does have a higher back. This species has a relatively large head with a superior mouth. The dorsal fin is positioned quite far back on the body and the anal fin is large and rounded.

Colour/Pattern Variability:
A base colour of yellowish brown with a dark brown lateral strip, the belly is white with a blue tint. It is not uncommon to find some specimens have black spots on their back.

The dorsal fins of adult males is almost orange and all other fins are yellow, females show little colour in their fins.

Behaviour:
This is an active, but peaceful fish

Husbandry:
This species can be kept in most environments, but does seem to do better in a planted tank with a gentle flow. An omnivore in nature that prefers diet of live food

Breeding Notes:
Generally not a problem to breed, ensure plenty of places for the fry to hide or use nursery tanks. Females will drop fry after about 28 days and depending on the size of the female, you can expect anything from 10 to 40+ fry.

BLA – Show rules

The exhibitor has a duty of care to ensure that the fish provided for the show are the optimum condition.

The organisers will not allow any fish into the show that is:-

  • Heavily gravid
  • Showing poor health
  • Showing signs of disease
  • Showing signs of damage
  • Showing undue distressed.

Disqualified fish will be moved to the treatment area by the exhibitor, who will be solely responsible for the provision of any and all treatment/care of the fish.

Preparing and transporting your fish for the show

  • It is a recommendation that you starve your fish for 48 hours before the show, this reduces the possibility of your fish producing waste and ammonia which can contaminate the water within the transport bag and the show tank.
  • It is a recommendation that your fish are transported in bags with rounded seals to prevent the accidental trapping of fish in the corners. If these bags are not available then tape will be used to round the corners off.
  • The bag will be large enough to hold sufficient water for the fish during the transportation to the show.
  • The bag will be tied off with a water/air ratio of one third water and 2 thirds air.
  • Fish should be bagged individually.
  • Use a suitable polystyrene box or other suitable means to transport the fish and extra water to the show.
  • Where necessary use a heat pack or other preferred method to keep your fish/water at the correct temperature.

Benching

  • Arrive in plenty of time to bench your fish, giving them sufficient time to acclimatise for showing after transportation.

Show tanks

  • All fish shall be shown in flat-sided rectangular Show tanks
  • The show tank must be of sufficient size to allow the fish freedom of movement and the ability to display at its full potential.
  • It is recommended that all Show tanks be fitted with clear loose fitting cover glasses
  • The container base should be coloured black and all other faces to be clear.

Water

  • All Show Tanks are to be adequately filled with water
  • Wherever possible the exhibitor will provide their own water to fill their show tank.
  • The Show Organisers will not be responsible for any loss of, or adverse effect on any fish caused by the water provided at the show.

Aeration

  • Aeration may be used by the exhibitor, but will be removed during judging.

Treatment area

  • Show organisers will provide a treatment area.
  • This will separate to the benching area.
  • All disqualified fish should be transferred to the triage area.
  • If this is not possible then the fish must be covered up.

The following facilities will be made available:

  • Aeration with airstone if required
  • A thermometer
  • Means of altering the water temperature.
  • A commercial stress treatment.

Bringing your fish to auction

Preparing your fish for sale

It is preferable to starve your fish the day before bagging for the auction, this reduces the possibility of your fish producing waste and ammonia which can contaminate the water within the bag.

Water and treatments

Where possible prepare and use fresh water for your fish to reduce the possibility of contaminates that exist in aquarium water.

It is advisable to add water conditioners to reduce toxins and relieve stress such as Ammo lock or stress coat in the bag. (Please adhere to manufacturers recommendations).  

Bagging your fish

To avoid the accidental trapping of fish within the bag, it is recommended that lots are double bagged with the 2nd outer bag inverted so the neck goes into the outer bag first. This ’rounds off’ the corners & strengthens the bag. When the lot is not double bagged it is recommended that the bag has a rounded seal at the bottom or tape is used to round the corners off to ensure the corners are rounded off.

The bag needs to be large enough to maintain the fish for at least a 24 hour period and will need enough capacity to hold one third water and 2 thirds air when tied off.

Pairs or more large fish should be bagged individually and joined together securely enough that the bags cannot be accidentally separated.

Large groups of smaller fish should be in bags large enough or split in to smaller and joined together securely enough that the bags cannot be accidentally separated. 

Transporting your fish

Please use a suitable polystyrene box and if necessary use a heat pack or other preferred method to keep your fish at the correct temperature.
Labelling your bag

You will be issued a letter prior to the auction. Label all your bags with this letter and the number of that particular lot for example A1, also include the name of the fish with any relevant collection or location data and also a  reserve price should you wish to set one.

PAIRS: – fish are normally sold in pairs – so that the purchaser can breed them. Please ensure that if sold as a pair, then the fish are a true pair. If not a pair – this must be stated on the form and bag.

Auctioning of Lots

Your box of fish will be placed below the rack and opened up alongside all other boxes. Bags will be taken at random and placed on the viewing rack for the buyers to inspect, once the auctioneers are ready the fish will be removed from the rack for auctioning.

Lots that contain fish that are dead, distressed or in the opinion of the committee are not fit for sale will not be auctioned.

Lots where the fish are incorrectly bagged, for instance the bag is deflated, too small for the fish or in the opinion of the committee are not suitable for sale will be returned to the seller.

All bidding will start at the specified reserve value for the lot or £3.00 and will raise in increments of 50p up to £10.00, after the £10.00 value is reached the increments will raise by £1.00. At the end of the auction the total sales per seller will be calculated. A 15% commission per seller is deducted before the seller is paid.

Limia melanogaster (Günther 1866)

Etymology:

Limia: Limia derived from the Latin ‘limus’ meaning mud, pertaining to the feeding habits of the fish

melanogaster meaning black abdomen.

First description:

Gunther A, 1866 Catalogue of the Physostomi, containing the families Salmonidae, Percopsidae, Galaxidae, Mormyridae, Gymnarchidae, socidae, Umbridae, Scombresocidae, Cyprinodontidae, in the collection of the British Museum. 

Synonyms:

Poecilia melanogaster Günther, 1866

Lebistes melanogaster (Günther, 1866)

History:

This species was originally classified in the genus Limia before this was made a sub-genus of Poecilia. Confusingly they have been reclassified once more into Limia, but are still referred to as members of Poecilia in much of the available literature.

Type Locality:

Not specified

Distribution:

Recorded in rivers near to Kingston and Spanish Town, Jamaica. Also found in other streams, lagoons and springs to the South and West of the island.

Group:

This species belongs to the subgenus Limia

Habitat:

Found in small shallow streams with dense vegetation over a sandy substrate.

Size:

Male 1.6″ (4cm). Female 2″ (5cm).

Description:

Black-bellied Limia has an overall grey body color with a blue sheen. Both sexes are marked with 5-8 dark vertical bars on the rear half of the body. Males have a smaller and more slender body.

Colouration:

Males: The male has a pale yellow dorsal fin, marked with two dark bands: one on the margin, the other on the base, the male’s caudal fin is orange with a dark band.

Females: the female has a clear fin with only one dark bar at the base. females have a large black patch on the belly                                  

Behaviour:

Peaceful and very active

Husbandry:

Prefers a tank with densely planted areas but also plenty of open swimming space hence the relatively large recommended tank size. Also appreciates some floating cover. Temperature should be in the range of 72-82°F (22-28°C) with a pH of 7.5-8.5

Breeding Notes:

Males are vigorous in their pursuit of the females, therefore a heavily planted tank which gives the females somewhere to hide is essential, also the addition of floating plants is also recommended.

The females can drop between 20-50 fry with a gestation period of 4-6 weeks. The fry are large enough to take newly hatched brine shrimp or powdered flake from birth.

A pale tan body colour and no visible gravid spot

Behaviour:

Peaceful, likes to live in groups of several individuals of a dozen or more.

Husbandry:

A well planted aquarium with open swimming space is required. The water temperature should be between 22 and 26 ° C and it is recommended than sudden temperature swings should be avoided as these fish can have an adverse reaction to them. A neutral pH of 6.8 to 7.5 and not excessively hard water is required.

Feeding is not difficult, all limias are omnivores and will eat flake, granular food, live and frozen with equal enthusiasm.

Breeding Notes:

Limia perugiae (Evermann & Clark, 1906)

Etymology:

Limia: Limia derived from the Latin ‘limus’ meaning mud, pertaining to the feeding habits of the fish

perugiae: named after Dr. Alberto Purugia

First description:

Evermann, B.W. and H.W. Clark. 1906:

New fishes from Santo Domingo. Proc. U. S. Natl. Mus., 30 (1478): 851-855.

Synonyms:
Platypoecilus perugiae Evermann & Clark, 1906 
Poecilia perugiae (Evermann & Clark, 1906)

Subgenus:

Limia

Type Locality:

Small stream in San Francisco Mts., Santo Domingo [Dominican Republic].

Distribution:

Southern slopes of Dominican Republic.

Populations:

Lago Enriquillo

Habitat:

Found in shallow water which is generally heavily-vegetated. It can also be found in brackish conditions and even hyper-saline lakes in certain locations.

Size:

Males to 30 mm SL, females 50 mm SL.

Distinguishing Characteristics:

The body shape and colour of is affected by the salinity of the water they are found in. The higher the salinity the smaller and less colourful the fish are. Body and head shape is also different with higher saline fish have a much more rounded head and a more streamlined body. 

Colour/Pattern Variability:

Males:

The Dorsal and caudal fins are pale yellow to orange depending on location, the edge of the fins is black along with some of the rays. The body colour is grey/brown colour which is offset by the way the scales catch the light and gives a metallic silver to blue sparkling effect. Stripes are visible of some males

Females:

The dorsal fin is without colour except for the black spot at the base at the back of the fin. The caudal fin is a very pale yellow/orange, all other fins are without colour. The body colour ranges from silver to pale yellow/brown with a white belly. A longitudinal zig-zag strip is also visible.

Behaviour:

A peaceful and active fish. In the wild can usually be found in large shoals.

Water conditions:

Limia perugiae is found in warm waters, therefore a temperature range of 72º to 80º is recommended.

A pH of over 7 is required, they will be happy in harder water. (Some populations actually live in salt lakes so some populations will tolerate brackish to seawater conditions and higher).

Feeding:

Not difficult, all limias are omnivores and will eat will take flake, granular food, live and frozen with equal enthusiasm.

Breeding Notes:

Males are persistent in chasing females, can be bred easily in the aquarium as long as there is plenty of food and plant cover for the fry to hide in as adults will predate fry.
Gestation takes around 4 – 6 weeks and broods of up to 40 fry have been reported.

Moving the female to a well planted nursery tank will help ensure good fry numbers.

It is thought that water temperatures can affect sex ratios, with higher temperatures producing more females.

Note: The genus Limia and Poecilia can hybridise with each other so where possible keep the species apart.

Neoheterandria elegans (HENN, 1916)

Etymology:                 Neoheterandria: from the Ancient Greek Neo meaning new, heteros, meaning ‘other, another, different’, and andros, meaning ‘male’.

elegans: from the Latin elegans, meaning fine, elegant, and handsome.

First description:        Henn, A. W., 1916 – Annals of the Carnegie Museum 10(1-2): 93-142 on various South American poeciliid fishes.

Common name            :           Tiger Teddy

Synonyms:                  None

Type Locality:                        Río Truandó,

The Río Truandó is a tributary of the Lower Río Atrato, Colombia

Distribution:               Neoheterandria elegans is only found in the type locality

Habitat:                      Found in shallow water with dense vegetation.

Size:                            Male 2.0 cm Female 2.5 cm

Colour/Pattern:          The overall base colour is an olive green with a series of black stripes on the flanks from below the dorsal fin to the caudal fin. The amount of stripes is different for each fish and range from 6 to 9, the stripes themselves can vary in thickness depending on the individual but the stripe directly above the anal fin is notably darker and thicker than the others and highlighted by a surrounding golden colour. The belly below the lateral line is silver/white.

Unpaired fins start out similar to the base colour of the body and as they spread out the colour fads and becomes a pale grey colour with more pronounced grey/blue edge.

Behaviour:                  Tiger teddies are a shy species that appears to do better in a species only setup, given a well planted aquarium that is heavily planted will bring them out, can be kept with dwarf corydoras and ottocinclus type fish and also shrimp are good companions.

Larger females can have a tendency to be aggressive.

Husbandry:                 Neoheterandria elegans can be kept in a smaller aquarium with dense vegetation. They only require minimal water movement so a sponge filter or similar is required. Water parameters are not too much of an issue with minimal hardness preferred with a ph. over 7 and a temperature of between 24 and 28 °C.

Water changes should be done regularly with 25% to 50% being changed weekly.

Neoheterandria elegans is a micro predator and will need small live or frozen foods to thrive, microworms, grindall worms and artemia nauplii. Will take crushed flake. They do have small superior mouths (opens upward) which means they will struggle to feed from the substrate.

Breeding Notes:         This species use the same method of reproduction as Heterandria formosa known as ‘superfoetation’ (superfetation in some literature) this is where the female can have multiple pregnancies at different stages of development running at the same time. The female appears to be constantly pregnant and will drop up to two fry every couple of days or so.

A mature sponge filter is a good idea to provide gentle circulation and infusoria supply. A good supply of infusoria supplemented with regular feeds of brine shrimp nauplii or small worms such as Walter worms will aid the growth of the fry.

The fry will grow fairly quickly and reach sexual maturity in as little as three months.
