Damselfish

Damselfish comprise the family Pomacentridae except those of the genera Amphiprion and Premnas, which are the anemonefishes. They can grow up to 14 inches (36 cm) long. While most are marine, a few species inhabit the lower stretches of rivers in fresh water. Damselfish usually have bright colors.
