Taiwan Bee Shrimp

A high-grade Caridina morph with bold black and white banding. One of the most prized ornamental shrimp. Requires soft, acidic water (pH 6.0-6.8, GH 4-6) and pristine conditions.

Blue Crayfish

A selectively bred color morph of the red swamp crayfish with brilliant blue coloration. Hardy and active, but will eat plants and harass tank mates.

Great Ramshorn Snail

The large, coiled ramshorn that doubles as a cleanup crew and a living water-quality alarm. Every individual is hermaphroditic, so any pair can breed - populations explode only when overfeeding creates a feast, and they shrink right back once feeding is cut back.

Blue Diamond Shrimp

A selectively bred color morph of Neocaridina davidi with solid, opaque blue coloration. Hardy and easy to breed, making them popular for planted tanks.
