Cull shrimp are neocaridinas that didn't quite meet the grading standards for a specific colour variety. They come in a random mix of colours and patterns, and you can expect some transparency along the body - this is completely normal and healthy. The photo shown is just a sample; every batch is different, and that's part of the fun. If you're looking for an affordable way to start a colony, stock a cleanup crew for a planted tank, or simply enjoy keeping shrimp without worrying about colour grades, culls are an excellent choice. They're just as hardy, active, and easy to breed as their graded siblings.
Culls share the same tolerance as any neocaridina and handle Brunei's tropical temperatures without trouble. They are ideal for cycling new tanks, stocking outdoor tubs and pond setups, or populating a planted tank's cleanup crew. Bred locally in Brunei Darussalam, they ship the short distance from our colony to your tank with minimal stress.
Culls breed at exactly the same rate as graded shrimp - often faster in practice, since a mixed colony is robust to any single colour line's quirks. Many keepers start a colony from culls and gradually cull toward a single colour, and some interesting grades appear from mixed lines over the generations.
Perfect tank mates for any shrimp-safe community, and their utility in cleanup duty is great value at this price. Feed as with any neocaridina: biofilm, blanched vegetables, and shrimp pellets. Check the delivery options and browse the full shop to build a mixed colony.
