ive had a yellow tail and a 3 striped and large domino together and added an orange tailed last !! the only two that really had issues were the yellow tail and the orange tail but the yellow tail is tuff and fast so it was just a chase game about it !! the yellow tail and orange are still playing chase but no harm done !! one on one and added together right
imo ya will be ok as long as there are plenty of hiding spots and not in a 20 gall heheh !! but thats with most fish
imo
