Overview

October 16, 2026 · Suggest an edit

The Cuban cichlid is one of the few cichlids living on the Caribbean islands and is the only cichlid species native to Cuba. Its silvery white or pale yellow body is covered with irregular black spots and blotches; its fins are spotted too. During breeding the body darkens noticeably and the contrast increases. Males reach 25 cm; with its strong jaws it hunts fish, crustaceans and snails. It is rare in the trade and is mostly kept by Central American cichlid enthusiasts.

  • Moderately hard, alkaline water; change 30% weekly.
