Hi Stardust! Appears the smaller one is stressed. How large are both frogs (snout to vent)? How large is enclosure? Does it has decor and hiding places so frogs can take a break from seeing each other? And just to rule out a possibility; have you done fecal tests for parasites on these guys?

Crickets are escape artists. Would not worry about loose crickets in house, they will eventually be found dead or alive. Do not feed your animals any recaptured feeders since they could become contaminated with stuff around house floor (i.e. sprays residue, etc.). Good luck !
