A new Caribbean snapping shrimp

Shrimp tanks are popular among freshwater aquarists, but marine aquarists largely view shrimps as afterthoughts. Why? It's not as if coral reefs aren't filled with colorful and interesting shrimps such as this newly described snapping shrimp.

Noise makes it hard for fish to school

Common theories are that the lack of predators or the relatively small size of aquariums discourage schooling. A new study finds that noise plays a big role. Noisy water = less cohesive schooling.
