Hi Andrew,

A 24x18x24" Exo is an approx. 44.88 US gallon sized tank. A general rule of thumb for averages sized frogs is 10 gallons of space per frog. You may keep between 4 to 5 red eyes in the tank. I have the same tank and I keep 5 in mine.

The colors sound as though he is of Nicaraguan parental decent. Do you have a photo you could share?

Breeding takes some time. You have to gain some experience with their basic care first. To breed them you'll need to build a rain chamber and learn how to mimic a change of weather with seasonal climate changes within the vivarium. They like to breed in the rainy springtime. I have spoken with many breeders but I currently only keep mine as pets.
