Betta Fish: Bean is finally in his 5g tank after a long recovery from having no fins!

his lights are off now and I plan to put some tannins in. hes very shocked by it all and is already trying to eat the snails in the tank, though I think hes losing interest in them lol. for context if anyone here hasn't seen him before, bean is a betta i rescued multiple weeks ago who was being sold in a cup, no filter or heater, with no fins, none at all. after being in his hospital tank hes grown back his fins and is super healthy! I'll attach pics in the comments of what he used to look like, though I warn its quite sad.
