My Panther crab just ate my frog!!! Help!

[Soota]

Hi all.

I have a 120 G freshwater tank, my current stock includes 2 discus, 2 angels, 1 bala shark, a tetra, a pleco, and I used to have a frog until today.

Earlier today I got the brain wave to get 2 Panther crabs, well... with 5 mins of them going in, one had a literal death grip on my small frog.

Are my fish in danger? if so, these lil buggers are headed straight back to the store.

Please help,

Dave
