My "Skittles" are healthy, lower grade Neocaridina shrimp that I cull and keep in a separate well maintained, natural scaped aquarium and are fed a quality diet. They're still very pretty. Shrimp come in mixed darker or lighter shades of 5 colours. $2 each or 15 for $25 Free floating plants included if wanted. Please ensure your aquarium is fully cycled before adding shrimp
