The Euxiphipops angels are mid-sized angels, much bigger than the Centropyges but smaller than the really big ones like Queens or Rock Beauties. They need really big tanks, and absolute top-of-the-line foods. These fish are pretty spectacular, but best left only to the experts. They are exceptionally prone to lateral line disease when things aren't kept just perfect. The sixbar is the least attractive of this genus, so naturally it is the hardiest and easiest to keep, although far from easy when compared to most other angels. If you have a 300 gallon tank with a miracle mud and caulerpa filter on it, along with ready access to a wide variety of choice foods, and the skill to properly quarantine the fish, then go for it! Make sure you have a grounding probe or two, and keep foot traffic near the tank to a minimum while the fish is getting used to the tank.

A 5-inch fish should be well out of the juvenile stage. The juvies have the same typical blue & white striped look shared by the other Pomacanthids.

All in all, I can't recommend this fish to anyone who hasn't kept large angels for a few years beforehand, and quite frankly, it angers me that the Euxiphipops angels are imported in the numbers they are without regard for their likely doom. These fish should only be available upon special order, I think.
