The Pink and Blue Shrimpgoby, Cryptocentrus leptocephalus, has a beautiful blue/white body with muted pink striping and vibrant neon spots across its face and back. It thrives well in tanks with plenty of live rock, a sandy substrate, and a tightly sealed lid to prevent escapes. The Pink and Blue Shrimpgoby is not aggressive but can be territorial with members of its own species in close quarters. They will build a burrow in the sand and spend much of their time swimming into the water column to collect food. They can form a symbiotic relationship with some species of shrimp, like the Pistol Shrimp. It is best to introduce multiple species at the same time to hedge against one of them becoming territorial.
