Bell cups are an excellent economical pod to add a bit of a naturalistic look to your terrarium. These make excellent accents, especially when used in small groups of three to five, in a terrarium. They are extremely woody and hold up quite well in a terrarium. Many dart frog keepers will also coat the inside of these with silicone to make a more natural tadpole deposition site for thumbnails and other frogs. This is definitely a pod that is good to keep on hand to add some interest to that unexpected terrarium build!
