I'm going on vacation this weekend. Luckily our travels take us right by a large fish shop. I'll be stopping on the way home so I may bring home a shrimp/goby pair. I hope so. I'm ready for something else besides snails and its been several weeks since I've set the tank up so I think it's time
I'm trying to add on the order of least aggressive to most aggressive. I'd love a yellow assessor. They had a couple on liveaquaria's Divers Den recently, but wasn't able to purchase b/c my tanks not ready for that fish yet. Will try with less expensive fish first.
