A new Caribbean snapping shrimp

By on

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

By on

Marine aquarists have all experienced it: Reef fishes that naturally school simply refuse to in captivity?

A new tetra with color-coded sexing

By on

Many tetras are difficult to sex. Often, differentiation comes down to fin lengths, subtle color deviations, or sometimes just the "fullness" of their bellies. But with Hyphessobrycon myrmex, the color between the sexes is unmistakable, and that's a good thing because this species is tiny.
