Do dart frogs eat gravel?

[itzjezze]

I know that most tree frogs may accidently eat rocks during feeding so smaller rocks are a no but are dart frogs just as special ed as tree frogs? lol I currently have a small rock bed area with rocks that are about the size of a thumbnail but I would like to mix in some smaller rocks about the size of fish aquarium gravel, will a dart eat these?

May be getting thumbnails so this question is also for them.

Its possible. If they were to swallow gravel it wouls surely kill them.

For Dendrobates, thumbs and Oophaga I would not worry at all, they are adapted to eat tiny prey captured with the tongue, a chunk of aquarium gravel is not likely to stick and would be spit out immediately if it did. It may be more of a concern with dart that will take larger prey in the jaws like Phyllobates, Epipedobates, Ameerega, etc. though I would still be surprised to hear of it happening even with them.
