Species Profiles
Nerite Snail
Neritina spp.
Nerite snails are the best algae-eating snails for freshwater aquariums. They come in beautiful patterns (zebra, tiger, horned, olive) and will not reproduce in freshwater — making them the ideal pest-free algae cleanup crew. A single nerite can keep a 5-gallon tank virtually algae-free.

Phenacogrammus interruptus
Congo tetras are the showstoppers of the tetra family. Males develop spectacular flowing fins with an iridescent rainbow sheen that shifts from blue to gold to green under aquarium lighting. They are larger than most tetras (up to 3.5 inches) and need a spacious, well-planted tank to display their full beauty. Peaceful but shy — they thrive with calm tank mates.
