Description: 10 (+1 DOA) x NeoRainbow Pack! Multi-Color pack of beautiful and diverse Neocaridina freshwater shrimp that will be great for a beginner shrimp keeper. They do well with peaceful smaller fish, but will thrive on their own. Babies will have a higher survival rate if fish/larger predators aren’t present. Drip acclimating shrimp is very important prior to new shrimp entering your aquarium!
