Dwarf Frog and Yellow Labids

Hello everyone!

I've had 3 yellow labids living with my two dwarf frogs for a few months
now. I've never seen the labids attack the frogs but I've seen the frogs nip
at the fish when they are right above them. Yesterday I came home to find
what was left of one of my frogs (not much at all). I feed my fish and frogs
on a regular basis and they are fed flakes, frozen brine shrimp and blood
worms. Are they more aggressive due to possible spawning?
