Rudles Posted June 20, 2021 Share Posted June 20, 2021 (edited) I noticed that my Cardinal Tetras are all hanging out at the surface possibly gasping for air. I turned off my co2 immediately. This was going on for possibly an hour at most. Will they be alright? Update. I put an airstone in the tank immediately. Looks like everything is alright. They have moved back down in the water column and seem to be acting normally. Edited June 20, 2021 by Rudles 1 Link to comment Share on other sites More sharing options...
