I've grown sheet moss in my white's tank a few years ago, but the first time I thought I saw one swallow some, I yanked it in favor of leaf litter. I know they can't swallow one of them! Lol I prefer sheet moss for smaller frogs like darts or mantellas. Besides, leaf litter is what they would encounter in the wild anyway.
Cushion moss is a real pain. It grows ridiculously slow, and you have to be very patient with it. Normally what happens is you put it in, then spore pods appear, then die, then the moss "dies" off and people rip it out because it's ugly. But if you are patient and leave it alone, in about a year, it will be beautiful again. Downside is waiting a year with ugliness in the tank. Lol
