Hello, this is my first post on here. I just got a 4" florida gar 2 days ago, he seems very healthy and has a good appetite. I didn't think much of it till now but his back is curved, it curved right at the very end of his back near is last 2 fins and tail fin. He still hunts but I can tell it's affecting him. He chills at the top of the water now... Been like this for a day now. This really sucks... I love gars and it took me for ever to even get one in a tank. Mainly I'm worried that he's going to die. Is there anything I can do to help him? By the way the tank is a standard 20gal. (Plan on throwing him in a 150 when he big enough).
