Yep, cyclopeeze freezer bars. Shooting them in their bumpy little faces with the turkey baster. Most of them are sticky enough to grab a few pieces. Since I added the first few ricordeas to this tank a few weeks ago, two of them have already grown new mouths and one has split in half. In my previous tank, the grew so slowly. In a year, I did not have any new ones. I was convinced they were just stunted by a) me not feeding them, and b) the water quality in my 240.
It's debateable whether or not you can feed them. Some say you can, some say you can't, that they are totally photosynthetic. I figured I might as well give the feedings a shot. As long as I keep my water quality up, it can't hurt anything.
