damselfish only aquarium

[mike31154]

A year or so ago I walked into my LFS in town & they had a tank set up with little in it other than a major school of yellow tail damsels. It looked amazing. They all looked like juveniles & of course as things go at LFS, it's no longer set up, so no idea how long they kept it going without issues.

I reckon you should just go for it. Inexpensive fish, so even if they eventually pick each other off, it won't be much different than what they do in the wild.
