You really need to head on over to the video tab to fully appreciate the uniqueness of these critters. They look like tiny little orchestra conductors setting their own tempo one moment and a prized fighter the next. Don’t worry, even if they have a boxer’s temper where he shrimp standing next to them is concerned, they are not a negative to find in our tanks. Those that don’t eat things like diatoms and detritus are predators on items such as tiny worms and crustaceans. They’re not too picky and will eat most anything that floats by them, grabbing it as it travels by.
