Disease forum would probably be seen more, but as my pleco already passed I thought this was more fitting. I had a small common pleco (bought him at Petsmart, that was what they were labled as) and put him in my 27g hex with my three angelfish. Shortly after, my angelfish became sick with finrot. I treated the tank with aquarium salt and melafix. I know now that this was what I did wrong. My question is, what hurt my pleco? Was it either or both of the remedies I used. Wondering for future reference, thank you guys!
