Blue Shell Dweller Cichlid
Blue Shell Dweller Cichlid (Lamprologus ocellatus) is one of the most fascinating and charismatic small cichlids in the hobby. These tiny fish live entirely in and around empty snail shells on the sandy floor of Lake Tanganyika — carrying them, arranging them, sleeping in them, and spawning in them. Males display beautiful blue-green iridescence on the face and flanks.
Feeding & Care Tip: Hikari Micro Pellets (soak briefly before feeding due to small mouth size) make an excellent staple. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Baby Brine Shrimp or Hikari Frozen or Freeze-Dried Tubifex Worms. Feed small amounts near the shell colony 2–3 times daily.
Lake Tanganyika is one of the world's oldest and most chemically stable lakes — its water is hard, alkaline, and crystal-clear. Replicating these conditions is essential. Use crushed coral or aragonite substrate to maintain alkalinity, provide excellent filtration and water clarity, and perform regular partial water changes. Tanganyikan cichlids are highly sensitive to poor water quality and must never be kept in soft or acidic conditions.
Provide empty snail shells — Escargot shells, apple snail shells, or purpose-sold cichlid shells all work well. Give several more shells than fish so each individual can choose and rearrange. Males hold a territory around a harem of shells occupied by females. Can be kept as a colony on a sandy substrate.
Shell dwellers are among the most entertaining cichlids to keep — watching them rearrange shells, defend territories, and care for fry inside the shells is endlessly fascinating. A colony in a well-designed sandy Tanganyikan setup is a genuinely captivating display.
