I hope I am posting in the right place with this, I am sure that my banded rubber frogs are Microhylids, if it is the wrong place sorry.

Anyway my question, I have 5 banded rubber frogs and because we are in Winter at the moment (and they were too young to hibernate) I have struggled to get pin head crickets and flighltess fruit flies so I have been feeding termites. Now I noticed the other day that one of the banded rubber frogs lost its right back foot. Now at first I thought it was the termites chewed it off so I panicked and cleaned their enclosure to get rid of all termites!!! But then on inspecting the missing limb it looked to clean (no wound or blood) so I can assume one of 2, either I bought her with a limb missing and only realised now (unlikely) or that she got jammed somewhere and blood flow stopped to that limb and the foot fell off. She is fine hobbling around but nothing severe, is there any thing I should put on it (F10 ointment?) and can frogs of this species re-generate limbs?

I know with research people do clip frogs toes so it it nothing drastic but being the first frogs I have kept I am neurotic.
