Not sure if this is the right section for this or not but any help will be apprieciated. I have this fish in my tank now. It's only about an inch long and I was wondering what kind it was because the pet store didn't know.
I have some--sometimes you see them called "celestial pearl danios" or the older name "galaxy rasboras."
They have their own website, complete with a forum: http://www.celestialpearldanio.com/
And, like all danios, they are a social fish who do best when kept in groups of at least 6 (of their own species), so you may want to get your guy some friends
