Green Terror (Andinoacara rivulatus)

Care basics

Green terrors are tough, colorful cichlids with bright blue green scales and an orange edge on the fins. They are hardy, but their temperament means planning tank mates carefully.

Give them plenty of room, strong filtration and rockwork or driftwood that breaks up lines of sight. Keep them with similar sized, robust cichlids, or keep one as a centerpiece fish.
