My baby Schoutendeni Munchkin, is swelling oddly it seems. I've included pictures from today, one a week or two ago, and the day I got her. I noticed a few days ago she looked odd and put the trio in the water, but today I woke up and she still looks sick and the water is super cloudy. I haven't tried feeding her yet today but yesterday she wouldn't eat, there are plenty of snails in her tank though. She's in a 29 gallon and her tankmates were two African butterfly fish, a blue panaque pleco l239, and an Amano shrimp, though I moved one of the butterfly fish out since he was pretty big and I thought he might've been stressing her out a few days ago when I did the meds. I have the trio, Prazipro, Kanaplex, Furan-2, and salt on hand, with just the trio in the water right now. Can anybody give me some advice an how to help her? Is this normal? She's pretty small, like 1.25 inches total in length, and my last puffer was full grown when I got him, so is this just a weird growing stage? I'm starting to get really concerned, and I'd really appreciate any help or insight!
