Sleeper Blue Dot Goby
The Sleeper Blue Dot Goby, also known as the Ladder Glider, Ladder Goby, or Sixspot Sleeper Goby, has a white body with bright blue spots under the eyes and mouth.

The Sleeper Blue Dot Goby is a beautiful addition to my 40-gallon tank. It’s active and curious, and the blue spots stand out well in the sand. I feed it daily with brine shrimp and mysis shrimp. It’s peaceful with my other fish, though I keep only one pair to avoid conflicts.

I’ve had this goby for three months now. It’s very active and enjoys digging in the live sand. I noticed it eats small crustaceans in the substrate. I keep it with peaceful species and avoid other gobies. It’s a great visual addition.

The fish looks stunning with its bright blue spots. It’s easy to care for and doesn’t stress other tank mates. I use live sand and feed it a mix of frozen shrimp and black worms. It’s become a regular part of the tank’s activity.
