So I have a king betta from petco his name is Leonidas I also have 3 angel fish who are still small, 2 Golden alge eaters 1 male blue high fin platy and 2 snails. I have a heated filtered planted tank (live) so far Leonidas hasn't tried to fight or attack the angels or anything else he doesn't flare up, an all around mellow guy, will this last? The angels haven't tried to nip or anything either they just mind their own business. I have pics of the tank in my profile. Any input would be appreciated!
