Thank you! The pet shop gave us medium crickets, but the frogs aren't fully grown yet. I would have brought small ones but I wasn't there when they were brought. It's a massive problem for me not going to look at them, I just want to keep checking the little frog is alright. I'll try my best to only look at them closely when I change the water every evening! I've only had them three days so I'll just hope it calms down and eats by then (:
