I got some blackworms today and dropped a few into the tank with my African dwarf frog & betta...
the betta caught one and ate it with great delight, frog knew something was up
but couldn't quite figure out what. The survivors of Firebolt the betta's
assault burrowed into the gravel and my soil substrate and vanished from site.

Anyone with experience with blackworms know if this is typical? Will they set
up a colony under there and emerge occasionally to feed my creatures? Or die
and feed my plants? Firebolt is staring at the spot where they disappeared with
great intensity, hoping they stick their heads out again.
