So I feel bad for my guy being all alone in his 5 gal tank I'm thinking of adding some cherry shrimp which I heard can go decent but wanted to know if there is any other fish or such I may be able to add in with my betta in his tank that he won't destroy? I was switching fish around and put 2 black neons in their while getting my other tank together and the little bugger ripped the tail fin apart of the one neon in under 5 mins so I'm not sure if that means no fish for oscar since he's a mean little bugger or if there is something I could add.
