Why is my fish keep going to the surface for air or something? its irritating listing to pop bubbles.?

what kind of fish is it? if it is a male betta, it is normal, he is making a bubble nest, this means he is ready to breed.



If it isn't a betta or a gold fish, you probably have an ammonia issue, making it hard for the fish to breathe, this will kill them if you don't take care of it.



it being a koi, it might breathe air. I'm not sure (seeing that we can't have here in Maine) . I would still test the water for ammonia, and get a filter if you you don't have one on there. It will help with the amount of air in the tank, decreasing the amount of time the fish is at the top of the water.Why is my fish keep going to the surface for air or something? its irritating listing to pop bubbles.?
I agree with the previous posters. Some fish do breathe air from the surface, including bettas and "cory cat[fish]s." Could you perhaps let us know what kind of fish you have, how big your tank is, and which fish is/are breathing from the surface? Does its normal breathing appear faster than normal? (Are its gills working overtime?)



One method of increasing the oxygen level in the tank is disturbing the water surface using an airstone/pump, hang-on-back filter, or powerheads. If this is a saltwater tank, a wet/dry trickle filter and protein skimmer will help a lot, too.Why is my fish keep going to the surface for air or something? its irritating listing to pop bubbles.?
That's exactly it, and that shouldn't be happening! This is a sign the dissolved oxygen in your tank is too low. If you don't have a filter, you need one. Hopefully you do have one, but that usually isn't the case here. If you do, and you have an airpump, I'd turn it up. Also, do a partial water change.



... four thumbs down? ok...





Addressing the other answers, very much right on. I didn't think of a betta, which was a pretty serious mistake on my part. If it IS a betta, then there is no problem.



Its a KOI? Then it is definately an oxygenation problem. Also, wtf is with the thumbs down... my answer is correct.
