. Its males are significantly larger than females, the reason being that males of the species collect empty snail shells for the females to breed in. Therefore, males have to be large and strong enough to transport shells, while females have to be small enough to fit in the shells. Immature males will form schools that may exceed 100 individuals. These schools roam around, leaving a trail of destruction as they feed on insect larvae, crustaceans, and juvenile cichlids.
