Lamprologus ocellatus

Lamprologus ocellatus is a species of shell dwelling cichlid endemic to Lake Tanganyika. It is a popular aquarium fish due to its small size, appearance, and intelligence. Juveniles measure about 6 millimetres (0.24 in) at hatching, while adults grow up to 5.8 centimetres (2.3 in) TL. They range in color from a light brownish color to a gold/yellow color. These fish, like all shell dwellers, live in snail shells. They live in colonies amongst each other and raise their young in the shells. Male Lamprologus ocellatus are larger, and have a yellow edge on the dorsal fin. Lamprologus ocellatus are identified as African Cichlids in the aquarium trade. They are not a beginner's species. Instead, they appear in the tanks of more advanced hobbyists who specialize in fish hailing from Lake Tanganyika. Lamprologus ocellatus can be maintained in aquariums as small as 5 gallons (19 l), although this would severely limit the number of specimens. One empty aquatic snail shell should be provided for each individual, along with a thin layer of silica sand. Sand is not required for these fish to survive in captivity, but it allows them to display natural behavior. Lamprologus ocellatus use propeller-like motions of the tail to bury the shells that they reside in. This cannot be accomplished with heavier and larger-grain gravel. These fish are not considered to be an aggressive species in captivity. However, they will defend the shells that comprise their physical territory. They have even been known to attack the hands of aquarists. Lamprologus ocellatus require the same water chemistry as other Tanganyikan species. The pH should be between 8.0 and 8.3 at a minimum (Lake Tanganyika's pH ranges between 8.7 and 9.4). Mineral hardness, or kH, should be between 12 and 14. Temperature should be between 23–27 °C (73–81 °F). Like all Tanganyikans, L. ocellatus are quite sensitive to the nitrogen cycle. The presence of ammonia or nitrite can prove toxic to them. For this reason, good maintenance practices should be used. Adequate filtration is a necessity.
