so one of my corydoras has what i believe is a bacteria infection. i'm treating it with paraguard and just gave him a bath at half dose of the suggested amount. but he lost a LOT of color, think close to what an albino corydora looks like. i won't do this again if it's super stressful and will kill him, but i also need this bacterial infection to get better. is another bath worth the risk? i've also treated the main tank where he lives with a half dose.
