I have a blue spotted Toby which I believe it the Papuan type. He is in QT with a coral beauty and decided to take a bite out of the coral beauty’s tail. The angel is fine now and I put a divider in there separating them. My question is, do you think this is a one off thing and likely not a typical occurrence? Maybe because of it being in a qt with not a lot of rock and maybe it become territorial. Or is this something that this fish will do a lot? Below is a picture of my puffer. Thanks
