Hello, I have been away for the weekend and I noticed my BN pleco (plec) with a bloody mouth and an odd air bubble like growth coming from one of it's gills? I didn't notice anything strange with him before I left for my trip this past weekend.

my water params: 55Gal/208L with 20G/75L sump 0A:0Ni:<30Na temp: 79-80F or 26.1C

It's been running for about a year now. Custom sump I've built myself. All other fish are healthy as far as I can tell. No odd or strange behavior among them. It is a bit overstocked due to having to deal with a tank tear down and not having another tank in hand I don't know how to really describe my tank but it's pretty heavily planted. I'll let the images do the talking. 20160215_095917.jpg 20160215_095936.jpg 20160215_095917.jpg 20160215_095936.jpg 20160215_095944.jpg 20160215_100336.jpg
