Thanks!

I saw them eating the 2-week old crickets, the crickets are about 1cm long. When the crickets are a little bigger it has taken them some time to completely consume it, but they don't seem to be having any trouble. I watched him use his little hands to push the cricket into his mouth.

My last tadpole is going to be ready for the frog tank by next week so I'll have to buy pinheads for him anyway. But it's good to kinda know what size of cricket they can handle. I've honestly never ordered crickets online because I'm in Canada and not sure how well that would go with shipping but perhaps I should look into it.
