Description

Chromis analis is a slender reef fish with a silvery to bluish body and a distinct yellow coloration on the tail region. Its streamlined shape is well adapted for constant swimming in the open water above coral reefs.

Behavior

The Yellowtail Chromis is typically found in large shoals hovering above coral reefs. It is highly active, peaceful, and constantly on the move. Within groups, a loose hierarchy may develop, with larger individuals often occupying central positions.

Special Notes

Chromis analis displays natural schooling behavior and adds dynamic movement to reef aquariums. However, in too small groups, intraspecific aggression may occur, so larger groups are strongly recommended.
