2 days ago, i turned the air pump off to do some maintenance and forgot to turn the thing back on. i woke up to my pleco at the top of the tank gasping. I quickly turn the thing back on and after a full 24hrs he is still at the top of the water. its almost like he has air in his stomach. he also seams to have a bulging eyeball. i dont know what to do at this point. can anyone help me?
