Hi, I got these fish a year ago and eere the first in the tank, but have no idea what they are! They were at my LFS for a charity donation... lovely fish and not caused any problems... any ideas?

Oh really? They've been really peaceful in our tank, we have 4. They we're bought as starter fish when we first set the tank up... and all pur fish's tails are all in one peace! Thanks.
