Betta Tankmate

[MDV39]

I bought a mystery snail for my betta because I read they are compatible. Today when I fed them I dropped an algae round for the snail. While he was eating it my betta came in and nipped him and started going after the algae. He didn't do that yesterday when I fed them. The snail obviously retreated so I took him out and put him in my 20 gal community. Should I nix the idea of having a tankmate for my betta and take this as a sign that hes aggressive.

Bettas are #1 pigs. I know some people keep mystery snails in with bettas no problem. I don't know how they feed them algae though. When I had my assassin snails in with the bettas Ludendorff constantly tormented them. Eventually he will get bored. Or the snail will learn to come out in the dark.
My bettas don't touch lettuce or cucumber so maybe you can try that for your snail?
But there is no reason not to avoid keeping a snail in there :) Snails have shells to protect them from nippy bettas. It might just take a few days.
