I was feeding him 1 full algea wafer and shrimp pellets every other day when he was in his primary tank. Right now I feed him half an algae wafer and shrimp pellets everyday. I've been doing water changes 3-4 times a week for the past 2 months since he got sick.
I've had my pleco for 7 years, he is about 8". I noticed got sick around 8/24/22, he had a tank mate an albino rainbow shark, about 5" who had just died and the pleco feed off the sick fish.
I was lacking on tank cleaning due to personal issues so it had only been cleaned a couple times within...
