Made a trip to PetSmart today for some things, and well- it happened. You guys probably know how this works by now.
Found him stuck in the back of the shelf, laying on his side and struggling to swim even in the little cup. He did seem excited and wanted to wiggle and dance as best he could, so I figured I'd give him a shot. Outside of what I think is a swim bladder issue, he seems otherwise active and curious with gorgeous, bright colors.
No name yet, but he seems feisty and likes exploring his half of the planted 10g divided he's in. I'll add some pics of him in the tank once he's a little more settled. Putting him in the warmer water definitely seemed to improve his color and condition, even after just a few hours.
I'm planning on daily PWCs and water testing, and have epsom salts on hand if I need to use them.
Here's to hoping he makes a full recovery!
