Compatible Invertebrates
4Blue 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.
R
Rabbit Snail
A large, striking freshwater snail with a conical shell and colorful body. Comes in orange, yellow, and dark variants. Active algae and detritus consumer, but slow breeder.
Golden Back Yellow Shrimp
A bright yellow color morph of Neocaridina davidi with a distinctive golden back stripe. Hardy, prolific breeder, and excellent algae consumer for planted tanks.
