Thanks Sakura8! Do you think it's okay to stop using the PimaFix at this point? It concerns me a bit because of what you mentioned about the labyrinth organ. I haven't used any since that 1/4 teaspoon day before yesterday.
Of course now that he's better, my newest (and smallest) boy is having an issue. He seemed fine yesterday and doesn't look bloated or anything, but he keeps bobbing to the top of the tank and can't seem to keep his back end down. I'm concerned because he seems to be stressing himself out trying to stay upright. He keeps breathing heavily. I've moved him to the cup he came in to keep him from having to struggle so much. I used tank water that had epsom salt in it. Not sure what else to do except not feed him for a bit.
I think these fish are determined to make my hair gray!
