I'm starting to think he might have velvet. I've used a flashlight to check him every now and then and he's always, since I've had him, had a slight yellow iridescent look to him under a flashlight. I checked him again this morning after his water change and there is more under his mouth than there was before and its gold for sure. The bumps on his sides could possibly be cysts? I don't know, this is my first time dealing with any of this.
I JUST finished with the maracyn meds, does he need to be in clean water for a few days before I start the other treatment? I've read that Parasite Guard and copper sulfate work but I can't seem to find anything copper on the PetSmart website. Is there a specific brand or preferred treatment beside something I have to order online?
The past 2 days he's been more active and all of the stated positive signs are still present so hopefully it's not too late!
