Can Anyone Help I.D This?

[Sib0t]

Hi All
I'm new to the forum, but not to the world of frogs.
I used to keep Agalychnis in my youth but for the past 25 years have been more into the invertebrate world than the amphibian one.
Here's a little background before the big question....

I used to volunteer my free time with an invertebrate wholesaler (the usual thing, Scorpions,Tarantulas etc etc for the pet trade and zoo's) we used to get a shipment in from a few places around the world a couple of time a year to stock up the breeding enclosures / gene pool. On one such shipment from Cameroon we found a frog that had been placed in a coke bottle and shipped with the invertebrates. As it wasn't something anyone in the company wanted I said I would take it home and care for the little guy the best I could.

Since then I have been asking a few zoo contacts etc if anyone could ID it, but sofar no one has.

So here's the question....Anyone seen one of these and know what it is???

I have had it 3 years now, its about 40mm long and changes colour from light green/ yellow to brown to black in only a very short time.
It always has the red lines on the back legs.

Thanks in advance for the input
