Ive had my tomato frog "Bob" in a 10 gallon aquarium with cocoanut bedding and exo terra terrarium moss, this was a bad idea. Bob became impacted and i had given him many warm baths for at least 10 minutes a day, after the fourth day he pooped the largest turd ive ever seen! i never buy that type of moss for larger ambush frogs anymore. now i use wild sphagnum that comes in large sheets that he cannot swallow.
