I finally managed to get my hands on my 4 Schistura denisonii yesterday, Mick got me these a while back but I haven't had chance to get over to pick them up before yesterday:
aren't they smart mate, the one with the mark on the head i think is the dominant male as no matter how much he ate he stayed the same girth.
btw they love digging bud but with looks like theirs, they're allowed.
