Ooeidozyga lima - Frog of Mystery

This isn't a particularly good photo of the frog so I'll add some desciption. Common names Floating Frog, Fat Floater, Indonesian Floating Frog Size This frog is about 1.5" in length. Feet All five toes on its back feet are webbed and each toe has a black claw. There also appear to be two spur-like projections on the heel portion of each back foot.  It has four toes on its front feet which have almost no webbing. All toes on the front feet are clawed. Face & Head Its eyes are lidded with horizontal pupils.  The eyes also close and depress to aid the frog in swallowing.  Its mouth is large and appears to be tongueless. Coloring The underbelley is light gold with no patterning.  There appears to a lateral line between the front and rear legs. Behavior This frog is not particularly active.  It will sit for hours in the position as shown in the photo.  I have observed it sitting completely out of the water for short periods of time and only when it was bathed in running water from the filter outflow.  I have never heard the frog "croak".  It has periodically made a "squeaking" sound but I have not been able to link the sound with any other obvious behavior or condition. Diet This frog prefers to feed from the surface of the water or the air.  It will eat live crickets from the surface.  I usually feed it bloodworms from the blunt end of a bamboo skewer. The frog will leap up from the water to eat the bloodworm from the skewer.
