You have received good advice and have lots of things to correct on your frogs enclosure. Need to separate those 2 unless you make that divider waterproof as Lija mentioned.

A 5-6 month old Pacman should be almost adult sized, if not. From your description as babies, yours are far from that and it's not good. Please get some night crawlers (Walmart's sport section) and add them to your frogs diet and do read this article as soon as you can: Frog Forum - Pacman and Horned Frogs - Ceratophrys - Care and Breeding . Good luck !
