I noticed something about alot of the worms that are fed to amphibians. They escape quite easily by some amphibians who are slow feeders. I tried using a deep high domed dish and I put the worms in there and all of them were gone within several minutes.
Just wanted to post something up about that. Also, ever noticed how its hard to put calcium/vitamin powder over the worms? Well I found out if you wet the worms then sprinkle the powder over them it actually sticks better. May seem like common sense. But even stuff like that can be overlooked by people sometimes.
