Twin Spot Signal Goby (Signigobius biocellatus)
Max Size: 3 inches
Reef Compatible: Yes
Minimum Tank Size: 10 gallons
The Two Spot Goby, also known as the Twinspot Goby, Signal Goby, or Crabeye Goby, has a white body with orange markings and distinct eyespots on its erect dorsal fins.
To keep a Two Spot Goby healthy, a 10-gallon or larger aquarium with live sand substrate and a populated refugium should be provided. Although it's not usually aggressive towards other fish, it can be territorial and may fight with its own kind, except for mated pairs.
Under suitable conditions, the Two Spot Goby can spawn successfully in an aquarium.
This species mainly feeds by sifting through the sand for food. Its diet should include a variety of live or vitamin-enriched frozen brine shrimp, mysis shrimp, live black worms, and prepared foods for carnivores.
