I bought a small order of Calci-Worms to try out. So far two of the three pixie frogs I fed them to have thrown them back up whole in their water dishes! I am concerned to say the least. Both of these pixies are new, one is a dwarf, the other a gaint. They are also being fed nightcrawlers, hornworms and dubia roaches and have yet to throw any of these up. Just the calci-worms. Is it possible I got a bad batch? They are completely healthy otherwise and show no signs of illness. I also noticed this morning the third frog I fed the worms to has changed his behaviour pattern, which is unlike him. I'm worried he will be the next one to throw the worms up.
