Alright, if he has a secondary infection, what should I use to treat him? I'm still using the coppersafe, will the other meds react to it? I don't think I can add carbon to this filter to get out the coppersafe. He is more active when there is more coppersafe in the tank- the few times I've forgotten to replace half of the meds when I do a water change, he gets all lethargic again, but he perks back up when the full amount is in the water. Unfortunately I can't raise my tank temperature, but it usually is around 78-80*F. I just did my daily water change today, and Rojo ate this morning (I gave him 3 pellets). He's been hanging around the top of the tank today, and he has seemed more active lately. I keep forgetting to turn the lights out since I'm so used to turning them on in the morning, but I'll keep that in mind for tomorrow.
