Green Brittle Starfish
The green Brittle Starfish is sold to newer hobbyists as an active specimen, but they aren't warned how predatory it can be. Excited by the smell of food in the water, this animated echinoderm will cruise the tank looking for its next meal, but that speed also puts other fish at risk of becoming prey. If this animal is target fed often, it may be kept with others in a reef tank, but most people would not recommend this as reef-worthy including myself. Not Reef Safe.
