blue puller

About

The blue puller (Chromis caerulea) is a small damselfish found across the Indo-West Pacific, from the Red Sea south through the Kenyan coast and into the broader Pacific reef systems. In the wild it forms loose, often large shoals hovering above branching corals, darting down to shelter when threatened and rising again once the coast is clear. That schooling behavior is one of its most appealing qualities in the aquarium. A group of them moving together in the mid-water gives a reef tank a sense of life that solitary fish simply cannot replicate. The body is a soft, even blue-green that shifts slightly depending on the light, never garish, but consistently clean and attractive. Like most chromis, it is considerably more peaceful than the broader damselfish family, though individual fish can still show mild territorial friction with conspecifics over time, so keeping a group of at least five or six helps distribute any aggression. It does best in a well-established reef system with mature, stable water quality, which puts it in the intermediate category rather than a first-fish choice. Provide open swimming space in front of the rockwork and it will use every inch of it.
