hey everyone!

I have a sick, Bristlenose pleco (Homework) in my 125 freshwater aquarium. Homework is not eating much and has a weird patch of somethin' or other on him. The tank parameters are 0=ammonia, 0=nitrites, and 20=nitrates; the tank has been set up for about 17 years. He's in there with African & Central American cichlids who are all sub-adults at this point, except for the Jaguar cichlid who is a juvenile. The temp. of the water is 76 degreees, there are no live plants, and I run a Fluval FX5 that gets cleaned 2X/year. The tank receives no direct sunlight; I perform water changes 1X/week just about religiously. The fish are fed NLS, spriulina, frozen bloodworms & beefheart, and occasionally feeders.

I did have a issue with velvet on the fish here recently, and I treated with Pimafix for a week; it cleared up. The pleco"s condition, however, improved but did not heal all the way. I've noticed that he hides and is not eating as much...

Could someone please help me as to what my next steps should be to get the lil' guy feeling better? Thank you.

Could be just stressed from the pimafix and/or recent infection. I’d try soaking the food in some garlic and refeed. If not better in a week then try dosing metronidazole to the tank. Any change in the color if its poop?
