The Red-margined Shrimpgoby (Amblyeleotris rubrimarginata) has bright red trim along its dorsal fins. Its long white body has tan bands with some speckling between the bands. Some also appear to have red spots on the first dorsal fin. This is a fairly newly-described species and is not yet well-documented so some regional or natural variations may occur.
This fish is best known as part of the group of gobies known as shrimpgobies. They form symbiotic relationships with certain pistol shrimp. These shrimp build and maintain a burrow for them both to live in, and the goby defends the lair and supplies food. Shrimpgobies are also minor sandsifters but will not sift as much as those generally referred to as "Sleeper Gobies".
These gobies will eat a variety of frozen foods and possibly flake and pellet. Gobies prefer a tank with plenty of rocky hiding places. They get along with most tankmates, but can be aggressive toward other gobies. Gobies are known jumpers; when startled or threatened, they have been known to jump out of uncovered aquariums. Always keep the tank covered and provide plenty of hiding places for this fish to retreat to.

Ratings & Reviews
Bought two of these guys to bond with small Japanese Red Pistol shrimp hoping one would pair with shrimp. Very pleased with these guys they both guard shrimp burrow one on each side. They do squabble a little bit but all ways seem to end up their own side of burrow. I also bought the shrimp at the Fish Place.
