No problem on using the name. I also thought about calling him Scaredy Smurf as when I first walk up to the tank he darts behind some rock to his hide out and then pokes out to see if it's safe.

I just got an email from a friend who works at Aquatek in Austin and he suggested trying an arrow crab on the red planarians or a dottyback. He said if I try the arrow crab, don't feed for awhile so that it will get hungry and start eating them. I'm sure this is still hit or miss like all the other solutions.
