KittenFishMom Posted January 24, 2022 Share Posted January 24, 2022 Recently, my peppered/paleatus corys have been dashing to the surface of my tank, and then dashing back to the bottom. It looks a bit like they are catching bugs on the surface, but the tank has a tight fitting lid, and there aren't any bugs under the lid. Is this some sort of mating display? Are they showing off for each other? They do not stay at the top as if they need oxygen. They seems to be acting normal in every other way. I would say they have been doing this for several days to a week. Any ideas? Link to comment Share on other sites More sharing options...
Ken Burke Posted January 24, 2022 Share Posted January 24, 2022 Corydoras will gulp air from time to time. It’s the same normal behavior we see in bettas etc. I have pandas, red sailfin, and pigmy’s. They all do it. Link to comment Share on other sites More sharing options...
AndEEss Posted January 24, 2022 Share Posted January 24, 2022 Standard cory catfish behavior. Now, if they are doing it very frequently, that could mean you have poor oxygenation/turnover. 1 Link to comment Share on other sites More sharing options...
sanford Posted January 25, 2022 Share Posted January 25, 2022 My daughter and I call it "dive bombing". Part of what makes keeping corydoras exciting. Link to comment Share on other sites More sharing options...
