Welcome . I just joined the forum a month or so ago and I have learned bunches already. Everyone has been very kind and helpful and they really know their stuff here. I have had red belly toads for years and just recently traded them for red eyed tree frogs. when I first purchased my toads the fella at the pet store also told me the same. So, I fed them mealworms and small crickets. One of my babies bloated up and could hardly walk or swim. I soaked him in a warm dechlor bath but it was too late and he passed. I felt awful. The next time I went to get crickets I asked my buddy who has had several types of frogs and toads and he said he probably had trouble digesting the worms and became impacted. So I sadly learned the hard way . I fed the others crickets from then on out and they did great, never got sick, and were healthy energetic little guys .
Small crickets dusted with calcium/vitamin D powder are best for them.
I hope you enjoy your babies and look forward to your viv!
