2 of my 6 dwarf puffers have been fighting recently. They have puffed up 2 times. There have been no serious bites so far except a bite out of a tail. Some of the baby puffers are getting quite upset by the fighting and one of the dominant puffers stop some of the others eating. Any ideas weather i should put the most dominant puffer in my spare 5 gallon or wait it out and see how it goes?
