Care basics

Tropheus graze algae from rocks in the lake, and dozens of regional color forms are traded. They are rewarding but less forgiving than many cichlids.

Keep them in a group in a large tank so squabbling is spread out, and feed a vegetable based diet. Rich, protein heavy foods can cause bloat.
