Ameca splendens (Butterfly Goodeid)

Dominant males are iridescent silvery-green with a gold-tinged belly and a longitudinal blue-black band along the midline of the flank. The tail fin is marked with a vertical yellow and black bands. Quiescent males are similar but their colours are less pronounced.

Females and immature males are essentially silver with black speckles. Because males and females can look rather similar when young, if the colours on the tail fin aren't obvious, it's best to go by the anal fin. On males this will be obviously "split" into two lobes; as with other livebearers, this modified anal fin is used to direct sperm into the female's body where the eggs can be fertilised.

An interesting species that is extinct in the wild, though fairly widely traded as an aquarium fish. Tolerant of a broad range of water conditions and temperatures, but because of its nippy personality, not suitable for communities with slow-moving or long-finned fish.


Fish information (behaviour and breeding):

Ameca splendens is one of the two most widely traded splitfins (family Goodeidae), the other species being Xenotoca eiseni. Both species tend to be fin-nippers, so aren't as widely kept in community tanks as the livebearers of the family Poeciliidae, such as guppies. But for the aquarist interested in oddball livebearers, these fish are well worth keeping.

In terms of basic care this is a hardy, adaptable fish that does well across a range of conditions, from moderately hard, neutral freshwater through to slightly brackish water (to around SG 1.005 at 25 degrees Celsius). It is primarily a herbivorous species that eats algae and soft plants, but it also consumes a broad range of invertebrates including water fleas, worms and insect larvae. Flake foods are readily taken, but some algae-based foods should be provided as well.

Males are intolerant of one another, and in small tanks it is best to keep just a single male alongside two or more females. In larger tanks (110 litres upwards) more males might be kept, but ensure that they are outnumbered by the females. Nonetheless, it is worth keeping multiple males so that their interesting threat displays can be observed.

Decorate the tank with rocks and hardy plants; soft plants will be nibbled if these fish get hungry. A fairly strong water current is appreciated.

Breeding is generally not difficult. After mating, the embryos develop inside the female for a period of about two months. Broods are rather small in size, typically around 10-20 fry are delivered. On the other hand, the fry themselves are comparatively big at birth, up to 15 mm in length. The adults usually ignore their fry, so provided there are lots of floating plants, it is easy enough to collect fry as you find them. They can be easily reared on powdered flake food and algae.
