Otocinclus macrospilus sick?
I've got 3 Otocinclus macrospilus in my 15g tank, all are very alive and eating well (cucumber, zuchinni and algea(wafers)). But one has something stange, most part of the bottom of the head is tinted bloodred, it even shows thru his normal color when you look from above..
