schmofam Posted May 17 Share Posted May 17 This isn't necessarily a "what's wrong" question but more a "is this bad?" question. I have had two guppies for months and they swim at the top of the tank most of the time. Sometimes they break off and go deeper to peck at stuff. I have read that means they need more oxygen. However, I have a bubbler and the levels are in good shape with the tank. Is this something to worry about? I did recently lose one but that was shortly after I added some plants. I think it may be related to that and nitrate levels which I have addressed. 1 Link to comment Share on other sites More sharing options...
