Hi
Hoping someone has an idea of what species this is.

They came from Guinea West Africa.
I've had it since Nov 25th 2014 ...
my importer in Florida brought it in about Oct 1st
(probably not an african bullfrog, because I read they change to frogs within 19 days )

... these are large , aprox 4 inch (10 + cm)
they eat algae and green spirulina flake food voraciously

they seem happy at 74 degrees F (23 degrees C)
