Yuck! Gillbert was kind of sitting on the top of his castle behind all of the grime on the outside of the tank. I'm going to have free time tomorrow so as long as I don't get overwhelmed by a wave of laziness, I should get everything cleaned.
Got Gillbert some new food. The pellets are a little bit larger but he seems to like them. These ones seem to float a bit better so less food ends up getting wasted.
