Hey all, just noticed my female BN has a red spot on her head, kinda looks like a suck mark, she is still doing everything she has always done. Eating great, water parameters are fine... Does it sound like 'hole in the head'? No pics sorry. It looks like the big male has bitten her but I dont know if he would, the other tank mates leave the plecs alone.... Any ideas?
