Premnas biaculeatus is one of the largest and most dominant species among clownfish. The “Golden Maroon” form is a selectively bred variant with golden yellow patterns or lighter color variations on a red-orange body. It is a very striking but characteristically strong species.

Points to Consider

• May be incompatible with small and peaceful fish
• More than one maroon clownfish in the same tank usually causes problems
• May claim an anemone and become overly protective
• Aggression increases in smaller aquariums
