Overview
Multies, as hobbyists call them, are probably the smallest cichlids in the world: males reach about 2 inches (4-5 cm) and females stay closer to 1.2 inches (3 cm). They come from Lake Tanganyika, where they live in huge colonies on beds of empty snail shells that serve as shelter and spawning sites.
The pale body is crossed by thin dark vertical bars, and the bluish eyes are surprisingly expressive. Despite their size they have big personalities: they dig constantly, defend their shells and pop out to inspect everything going on. They are perfect if you want to watch complex social behavior in a fairly small, species-focused tank or alongside a few compatible Tanganyikans.
Care and tank setup
A trio or small group does well in a 15-gallon (60-litre) tank with a wide footprint; for a real colony, 25 gallons (100 litres) or more is better. The substrate is key: 2-3 inches (5-7 cm) of fine sand and plenty of empty shells, at least two or three per fish. Keep the water hard, alkaline and stable in a cycled tank with gentle filtration and a heater.
- Diggers: they move sand around their shells nonstop and will uproot rooted plants. Use anubias or Java fern on rocks.
- Tankmates: ideally a species tank; in larger setups, cyprichromis or small julidochromis that use other zones.
- Shrimp: not compatible; they eat shrimplets and harass small adults.
The most common mistake is providing too few shells. Without enough hiding spots fights escalate and subordinate fish have nowhere to retreat.
Feeding
Multies are micropredators that pick zooplankton from the water above the shell bed. They accept fine flakes and micro pellets for cichlids, but keep better color and condition with small live or frozen foods such as cyclops, baby brine shrimp, daphnia or chopped mysis. Several small feedings a day beat one large one.
Breeding
They breed readily when there are enough shells. The female spawns inside a shell and tends the eggs, while the male guards a territory that often includes several females. The fry stay within the colony and take baby brine shrimp. Over time one pair becomes a sizable group, so plan how you will manage the extra fish.
