I recently started an aquarium, let it cycle and have added 6 fish (5 Cardinal Tetra's and one Bristlenose Pleco. The Pleco has what looks to be a white/blue"ish" sore(s) on the side area of it, near the mouth.
I have taken a few pics (although they aren't the best), here they are. I am wondering if anyone can let me know what they think this might be? Any help is greatly appreciated.
He always seems to be flapping all 4 of his side fins too.
