Hi all, my res has gone underwater and almost looks as if hes choking, his throat puffs up and he opens his mouth as if hes choking..he does it over and over then i disappear for a while and hes basking.
Hes perfectly normal when basking, havent noticed anything wrong...Just noticed this today that he was doing that underwater..
What do you think it is? I put the water temp to 86F..just to keep him warm..I also forgot to mention hes about 2.5inches and roughly a year and a bit..
