Help guys, im new here i just made an account now and i need help a couple weeks ago my redtail catfish had a swim bladder problem but he was treated and it was over but 3 days ago he keeps on floating to the top of the tank has weird wrinkles on his skin aswell as on gill is curling and wont eat even if he does he throws it up. And now my gator gar yesterdag has bumped his nose on something and cut it open now today he floats to the top with his bottom jaw hanging slightly open or breathing very heavily aswell as now his eyes are becoming very cloudy. I have just put in some medicine like an hour ago and ive had these fish in this tank for 2 years with continous water changes why are they getting sick all of a sudden.
