Guh. I know. The state of his tail was what drew me to him in the first place. I hope it's all rot and not tail biting. That drove me crazy with Jalen lol. Luckily he's stopped.... FOR NOW.
I gave the new guy a betta pellet and he about choked. I'm gonna have to cut my bloodworms in half or something when I feed them to him.
keep his water clean. you don't have to add aquarium salt every day, i'd do it just the first few days. he's been tail biting, and lack of clean water caused it to get infected(the rot). the space and attention will stop him, and if not, add many plants, and redecorate his tank at every water change. that's how i got Dante to stop. :3
