Blind Cavefish

Care

Blind Cavefish are best maintained in groups of at least 6 specimens, in a darkened rocky-themed aquarium to mimic their natural habitat of underwater caves. They are a very active species and will require a tank at least 36” long. The aquarium should be well covered as these fish can easily jump from an open tank. Many aquarists prefer to house Blind Cavefish in a species-only aquarium as they often nip at other smaller, more peaceable tankmates. Blind Cavefish navigate their way around the aquarium by use of the lateral line organ. Food is easily located with their heightened sense of smell. May also be seen on sale as the Blind Cave Tetra.

Feeding

Flakes, micropellets, frozen foods such as mosquito larvae, brineshrimp, Mysis shrimp etc.

Breeding

Water chemistry is unimportant, provided that it is clean and of a subtropical temperature (18-21 deg C). Blind Cavefish will spawn over Java moss/spawning mops and the parents should be removed once the female is exhausted of eggs. After 24-72 hours, the eggs will hatch, and the fry become free-swimming after 5-6 days. The young can be fed on crushed flake food and baby brineshrimp. The fry will be born with eyes, but their sight will deteriorate rapidly and the eyes will become covered within a few weeks.
