Hello everyone, I used to come on here years ago and usually got some good feedback so, here I am again. I adopted a wild caught DBT about the size of a quarter a few months ago after he was taken from the Jersey shore and dropped at a friend's pet shop. Anyway, let me get to it. I never noticed until the past few days that he's randomly doing this thing when I walk up to his tank where it looks like his neck is puffed up. He only does it when in the water with hi head out. My guesses where either a way of taking in air or what I thought more likely, a type of defense. I haven't been able to find this on any care sheets so, I figured I'd ask. Thank so much for all of your time and hlep. Be well and happy always
