Nice tank Will!!! I'm going to have to come get some frags, I can get you some off the ones greg gave me if you want, but it doesn't look like you have much room left.

As far as feeding a brain, you can spot feed it by cutting of the top of a two liter bottle, leaving the lid off, place the cut off top over the brain and then squirting the food onto the brain through a baster or something similar. then take the bottle top after its done eating.
