My new HM plakat I got from petco just 4 days ago, and was doing fine then, has now become drained and has clamped fins. I had him flare to check out his fins and saw in her tail is a perfect hole! His color does seem a little pail too, so I am treating him now for fin rot. He is in his own heated bowl with a dose of aquarium salt and a dose of BettaFix. Is there anything else I should do for him? The other fish he was next too all look fine and active, but I still treated them and will do a water change in the morning. I did a 25% change today as well. Mind you this is my new tank as well.
