Vietnamese Mossy Frog Theloderma corticale

A few years ago, a friend of mine gave me a price list that had these frogs listed on it, along with some photos. I was fascinated, the frogs were beautiful, but I was a little put off by the price, which was $400 each. However a couple of years ago they began appearing at about a third that price, and I finally decided to try a group of them.

I have thoroughly enjoyed them, they have proven relatively easy to keep and breed. The colors are amazing, and they have a quiet call that is not at all what you would expect from a frog!
Update: The above was written back in around 2003 when we first started breeding these frogs.  Over the  years, we have continued to enjoy working with this frog, and find them to be very robust frogs, that are easy to breed.  However there are a number of issues with these frogs that complicate husbandry and breeding.  In brief, the frogs seem to be temperature sex determined, which, as far as I know, is a first in an amphibian.  Males are produced almost exclusively if tadpoles are not kept in the low seventies or below.  The second issue with these frogs is that they seem to be prone to bacterial infections, in particular as juveniles.

Terrarium Preferences
Low sixties to low eighties. Ideally mid seventies. Moderate These are good size frogs, and should have a fair amount of room. A thirty gallon "breeder" style tank should be the minimum size for a small group of these frogs. They do require a terrarium with plenty of water, and a pool that makes up most of the bottom of the tank is needed. Moving water is not required, but filtering it will help in keeping water clean.
Visibility in the tank
Groups of these compatible
Up to about 3 inches Good. Often rests during the day in view….if you can spot them! Yes, do well in groups as long as they are not overcrowded. Some issues with females being drowned by over enthusiastic males have been noticed, and the frogs may be safer and more productive in pairs.
Experience Level
Compatible with other species?
Beginner, but plenty of puzzles for the intermediate and advanced hobbyist to work out! Caution should be used, any frog or other animal that is small enough to be eaten will be.
Breeding :
Status in Hobby
We have bred them with good results in groups, however they can also be bred in pairs. See note in group compatibility section. Fairly common, however issues with scarcity of females may lead to issues with the frogs availability in the future.
