African Dwarf Frog

[Geoff]

Amanda and Phoebe, are the tops of your filters flat and level, or just slightly below, the water's surface with the frog's back slightly arched downwards so that their heads protrude just above the water? If so, I doubt that it's anything to be concerned about. It's one aspect of Hymenochirus behaviour that's been documented and is referred to as "burbling" because the frogs seem to gulp air at intervals. Under more natural conditions the frogs do this floating on top of vegetation at the water surface.

Alternatively, if what I've described above is different to what you're observing and the frogs are completely out of the water then there are a couple of other possible reasons I can think of for them behaving that way. The first one is that the filter might be too powerful for the volume of water. I've posted about this elsewhere on this board at: http://www.frogforum.net/aquatic-cla...e-filters.html

The only other circumstance I can think of when Hymenochirus frogs are inclined to try and leave the water is when there is something seriously wrong with the water and they try frantically to try and climb out the tank - but I doubt that's the case from what you've described.

(The paper in which "burbling" is described is: On the behavior and breeding biology of the African pipid frog Hymenochirus boettgeri by G. B. Rabb and M. S. Rabb (1963))

I think that's your answer pretty much covered. This is why I use the forum. Kudos to Geoff

When I kept ADF it was not uncommon for them to perch ontop of the filter or ontop of a floating log I had in the tank.

that looks like a clawed frog Jen
