White Cap Goby
The White Cap Goby is prized for its unusual and beautiful, stark coloration. Its body is a black color, but it is the thick white band on its head that places Lotilia graciliosa in a class of elegance wholly its own.
Native to relatively shallow reefs, wild specimens of the White Cap Goby inhabit open sand areas dotted with rubble near the base of reef structures. In the home aquarium, the White Cap Goby does best when housed in similar habitats. Like other Shrimp Gobies in the Gobiidae family, the White Cap Goby digs shallow burrows in sandy substrate and seldom strays far from its claimed territory. Instead, most prefer to perch on the sand just outside or hover in the water column directly above the burrow entrance.

The White Cap Goby is a striking addition to my reef tank. Its white head stands out beautifully against the dark body. It’s active but not aggressive, and it settles into its burrow quickly. I love how it adds a unique visual element without causing disturbances to other fish.

It’s a beautiful fish with a distinctive look. I noticed it digging in the sand and perching near the edges. The tank setup needs to be sandy, which I already had, so it adapted well. A little shy at first, but now it’s regular in its movements.

This goby is a true eye-catcher. The contrast between the black body and white head is stunning. It stays in one area and doesn’t stress other inhabitants. I’ve kept it for over six months and it’s thriving.
