I don't know if this would belong here but couldn't think of a better spot. But anyways this morning I was watching my frogs swim around in my tank (african dwarf frogs) and I noticed all three do the same thing. They stay at the bottom then swim to the top of the water flot their for a second and swim as fast as the can to the grown, then do it over and over again. And I watched them for about 30 mins and all three did it. And I was wondering if thats normal? Like maybe is my tank to small? Are they just swimming up for air? Could it be something worse? Or maybe I just got weird frogs. Btw their is three and their from 1.5-2.5 inch's long and I have them bythemselves in a 10 gallon tank. I did used to have some goldfish in their with them, but the goldfish always kept eating their food. Maybe could it be from me taking the fish out? Doubt it but you never know. Sorrie about the long post and all the questions, hope someone can help me out. Thx in advance
