Hi Froggiestlye thanks for the reply.
I have 3 Green and Golden Bell frogs all of them are about 4 months old. My frog Camo is the biggest so far at 3.2cm and the cricket was 2cm. Normally my 2nd biggest frog who I haven't been able to measure yet but I can see is smaller takes on crickets nearly 3cm and wins.

By woodies/roashes do you mean woodlice(sorry diffrent country diffrent names)? If you do I have a colony set up in the enclosure which is their staple diet I know that their shells are high in calcium which is good. I throw in 3 crickets and leave them and when all 3 have been eaten I put another 3 in sometimes theyhave lasted a week with only one eaten so I put them back in with the other crickets. Yesterday I saw a pair of crane flys and thought those would be easy food it took about 5 mins of jumping up high to eventually get one but then Tim Tam came out of nowhere flying through the air and grabbed the other on Tim Tam is about 2.5cm.
