My mida began fight my red terror today after I changed water. they were friends before this and now the red terror is avoiding the midas now. she has to stay away from the bully. what can I do? midas is also chasing the other fish in my tank. Can I put midas with my red belly pirahas or put rT with rbp? I only have two tanks. those rbps are only 2 inches and midas and rt are both 4 inches.
