As ayala said too much water change will stress him aswell, either stick with the 100% daily...or do that every other day with 50% change in between.
Also picking a small piece of your hornwork would help the rid ammonia aswell. Since hornwort is fast growing and doesnt need alot of light it'll be just fine...it's a very hardy plant.
F.M.L.... I just literally added him back to the tank... XD
He still has a little bit of gravel, and plenty of place for the BB to grow... I'm going to snip some of my hornwort and put it in there, though I hope the salt doesn't kill it first!
I just got a good look at Bo's side, and it's a raised bump with some white sticking around the edges. Columnaris doesn't do that, does it?
It's like a little node protruding from his side... a bump of sorts. His behavior is still the same, so...
Aquarium salt and double dose of API stress coat is what he's swimming with, right now.
