Hello there, this is my first of possibly many posts on this forum,

Before I get into any detail, here are the parameters and details of my tank:

-Ammonia is 0, Nitrites are +0.3/ppm (at the moment), Nitrates are at a safe level
-Tank is Pentametical 60L (14us G)
-Substrate is small-large gravel from a petshop
-Two filters, on lowest setting; one is a stingray, the other is a fluvial. I will remove the stingray once cycling has stopped.
-Nitrogen Cycle is almost complete, Ammonia is being converted into Nitrites and they are lowering and turning slowly into Nitrates
-Plants are live, Elodea Canadiensis
-Lots of hiding places (not sharp, of course)
-Temperature is constantly 20'c
-Fed frozen bloodworms and very small Repotmin pellets
-Water changes every week, 20%

For two weeks, I've had them in with three goldfish, who were finally put into my pond so now they're on their own in the tank.

Now, info about my frogs:


Two African Clawed Frogs (Xenopus Laevis), anywhere from two weeks to a month old, they're about 1inch in size. Sex is unknown at this moment in time.

Now, I think that is all the information needed for the following question:

Is it normal for them to 'hover' near the top of the tank?

I've been studying them for a few hours a day, when I first got them, they were always hiding and only came out at night and when I fed them (as expected). But ever since I've removed my fish they seem a lot more active and playful, but I've also noticed is that they're always near the top of the water instead of being at the bottom, why is this?

Thanks for any help.
