The Blue Chromis is a very peaceful and active fish from the Caribbean. These fish reside in the upper part of the aquarium and will help bring out more shy species that normally hide. A shoaling fish, Blue Chromis should be maintained together in a group, and make a bright addition to the reef or fish only aquarium that is 30 gallons or larger. The Blue Chromis feeds on a variety of meaty items, herbivore preparations, and flaked food.

The diet should be varied and consist of meaty items, herbivore flakes, and frozen preparations. Using vitamin-enriched foods may help to preserve the bright color.

Approximate Purchase Size: Small: 1/2" to 1-1/4", Medium 1-1/4" to 2-1/4", Large 2-1/4" to 3-1/4"

Customer Testimonials

Richard L Corpus Christi , TX
Mine was a very deep blue color, unlike the picture. Mine were dark blue and black. Nice looking fish, and very peaceful. They stay together for the most part.
Jennifer T Santa Maria , CA
We love our blue reef. We had been seeking one for over a year and bought one from Live Aquaria, he's awesome! Thanks a bunch! He doesn't get along too well with our green chromis, I don't know why.
Josh P Bay City , MI
Great fish. Arrived in good condition and is thriving in the DT after QT. Nice blue color, just like in the picture, without the aggressive behavior of damsels.
Brandon Nguyen Houston , TX
So far it’s been a few weeks, and my blue reef Chromi is doing fantastic. He buddies up with my blue green chromi and they would swim around looking at me for food. The fantastic blue coloration makes it stick out in any reef aquarium. A unique uncommon fish that will catch eyes.
