Adding a new frog?

[Mentat]

It would be CB and what are the fecal exams for?

A fecal exam will determine if frog has parasites (worms, protozoans, etc.) in their intestines. CBB frogs have less chance to carry, although some do. Due to some parasite life cycles; a minimum of 2 fecals done 2 weeks apart is recommended. If your frogs are healthy and parasite free and the new frog has them, you could infect all from being in same enclosure or sharing items like cleaning equipment. Good luck !
