just bought 3 red belly put it in the tankwith my black , my black started fighting 1 at a time then the reds were fighting back then they stopped do u think they will get along. my black is a 7inch and the reds are 10inch 9 and 7,its been about 10 hoursso far no fighting. i took my black out and put them all in at the same time and mixed the gravel around and the wood around so he wouldnt think its his home what do u think will happen
