I brought this betta home about 2 hours ago from petco. He looked really sad and depressed an not in the best health. His cup that he was in was all cloudy and had nasty stuf floating in it, I had to take him home.
Right now he's in a 1 gallon tank. It's warm out so the water is about 76 degrees. I gave him a hiding place and a plant. As I'm typin this right now he's swimming down for the first time since ive gotten him. He doesn't look like he has fin rot or ick but he has clamped fins and they're really scrawny. Other than just now, he was floating at the top of the tank vertically. I added in some aquarium salt and the water that's in the tank is from another cycled fish tank I have.
I've saved other bettas but is appreciate any advice.
Here's a pic of him (if it decides to work)
