So I noticed this critter nudged between a rock and the glass. Took a few shots of it and I was hoping you guys could help me identify this. It's a shrimp-like creature, but it seems to have appendages that could evolve into a club or spear. I don't even know. I just think it's fascinating this critter is in my tank.
