Humpbacked Limia (Limia nigrofasciata)
The Humpbacked Limia is a peaceful, active shoaling fish that can be kept in a species only aquarium and flourishes in the planted community aquarium. These fish will get along with other peaceful fish, but it may prey on dwarf shrimp. Larger, temperate invertebrates can also make excellent tankmates. However, these fish have been known to nip and tear at the fins of other livebearers.
The Humpbacked Limia is best kept in groups and prefers neutral to hard water. It typically will not prosper in very soft water. Also, males will bully each other, but if the males are equally matched no damage will come of it. However, frequently the dominant male will harass smaller males until they depart, so often only one male will survive in a colony.
Although this fish is quite hardy, they do not tolerate the slightest touch of ammonia in the water so because of this as well as the high price tag they are not recommended for the beginner aquarist.
Its body is a blueish-grey colouration that displays several vertical black stripes and frequently has bright yellow colouration on its throat and fins. You may also find dark marks on the caudal fin. Unfortunately, as the male matures its body outline becomes less attractive. Their black-edged dorsal fin enlarges, and even the front of the back develops a hump.

Photos of the Humpbacked Limia
Humpbacked Limias are endemic to Haiti and the Dominican Republic in North America. They inhabit shallow waters in streams, rivers and lagoons that are generally heavily-vegetated with aquatic plants. It usually swims around in large shoals. You can also find these fish in brackish water conditions at several locations.
What to feed the Humpbacked Limia
The Humpbacked Limias are not picky eaters and will accept most foods offered to them. You should provide these fish with high quality dried and frozen foods making sure you balance that out with vegetable matter whether it be fresh or in a flake form.
How to sex the Humpbacked Limia
It is relatively straightforward to distinguish males from female Humpbacked Limias. Males will maintain a much stronger colouration and have the signature gonopodium. They also develop the characteristic hump as well as a modified anal fin and are generally smaller than the females. In contrast, females are more extensive and much duller.
How to breed the Humpbacked Limia
It is effortless to breed the Humpbacked Limia if you avoid soft, acidic water. They reproduce in typical livebearer form. As with similar species, the males can be somewhat constant in their chase of females. It would be best if you kept several females to every male to dissipate this. Areas of thick planting for the females to seek shelter in will also help.
Gestation takes between 6-8 weeks, and they can produce broods of up to 50 fry each time depending on their size and health. The adult fish will predate on the young, so to save more fry it is advisable to remove the gravid female to a separate tank and allow her to give birth there before returning her to the main aquarium.
The fry is quite big, so they will be able to accept powdered flake food or brine shrimp nauplii from birth. The young proliferate if well fed and can attain adult size in under six months.
It is believed that temperature may play a part in the determination of sex of this species, so if the water temperature is higher, more young fish will develop into females.
