I currently have one male betta in a 2.5 gallon tank. My tank has recently had this weird issue with what I believe is white hair algae. And I was wondering if I could add a small snail in my tank? I don’t know if my betta would be aggressive towards it or not, he’s never flared at anything..yet But is my tank too small to have another little tank mate? Just curious I don’t wanna stress the poor guy out, I’ve only had him for a month! I’m still quite new to fish keeping!
