they were really battered when I got them, very unusual for my LFS. All had torn fins, and once I got them back had the worse outbreak of ich i've seen - looked like snowmen. Got rid of the ICH a few days back and they seems to be getting into health slowly. One odd thing tho is that they all have a bit missing from the dorsal in exactly the same place (about 1/4 the way up from the back). Wondered if they'd been pinched out to ID them somehow.
