Angelfish fin rot

[cocopebbles526]

Hi guys! I really need some help. I have an angel fish with what I think is fin rot. I'm new to aquariums and never dealt with disease before. The edges of his fins are black and ragged. I've tried raising the temp and using more stress coat during water changes. I have a pleco in the tank with him. What medications can I use for it that won't hurt the pleco and how much?


Tank specs
75 gallon
Aqueon 60 and top fin large canister filters
0 ammonia 0 nitrite 30 nitrate
7.5 ph
1 angelfish, 2 blood parrot fish, 1 convict, 1 blue ram, 1 firemouth, and 1 common pleco.

Can you share pics? Anyone else in the tank?
