first off, allow me to apologize for us running the inside joke about the spaghetti. i take full responsibility. i am sorry to have hijacked your thread like that. pin heads are fine for FBT's, in fact, they are better than the large ones. i don't own any, but maybe someone can chime in on a good amount to start with.

as far as the gut load, i have never used that product. i always just tossed some oatmeal in the cricket tank from time to time whenever i watered their sponge.
