keeping them with whites? that is just retarded. Whites are so heavy and aggressive they would constantly pounce on him and if they were big enough eat him! They would stress the poor frog out so much it would die from stress alone.
It was a bit silly buying something without doing research. Also why did you buy it if it was emancipated and lethargic? It may be too far gone for it to recover, but make sure you do read my caresheet and keep the frog dry ignore the caresheets that say to crank up the humidity to 70-80 thats just wrong, they are only exposed to that during the breeding season not all year round! It will cause a stressed frog to be easily susceptible to picking up a bacterial infection brought on by the warm humid environment.
Also don't put me down as some fanatic I have alot of experience with these frogs. Frogs, ESPECIALLY red eyes can be extremely difficult to care for if you dont have experience with them and their behaviours/characteristics.
