I'm not sure if this is the correct place to ask this but here I go!

I'm pretty new to dart frogs; I only got my four azureus about a week ago. But we have a bit of an ant problem at the moment and the ants seem to have found something worth taking in the tank I set up for the frogs. They're absolutely everywhere in there. I read somewhere that ants can make dart frogs poisonous again. Does that count for all ants or just the ones that naturally have a bit of toxicity? My infestation seems to be just normal black ants. Also! If the dart frogs eat them will any harm come to them? or should I start figuring out a way to keep them out of the tank?

Thanks!
