I recently upgraded from a 25 gallon to a 60 gallon. My RBTA took a trip through the powerhead a few days ago. Kind of looked like it was filleted. Seems to be recovering OK, but half of it has slithered through the slits of the isolation container. I can't tell for sure where the foot is or the mouth, or whether it is splitting. Any ideas on what to do? Can I cut it into two pieces, or try to pull it back through the slit? If it is splitting on its own, I don't want the escapee to take another trip through the powerhead!
