Goby - Twinspot

The Twinspot Goby, also known as the Signal Goby or Signigobius biocellatus, is a small and fascinating fish known for its interesting behavior and symbiotic relationship with pistol shrimp. Here are the general requirements for keeping a Twinspot Goby:

1. Tank size: Twinspot Gobies are relatively small, but they require a tank with a minimum capacity of 20 gallons (75 liters) to provide enough swimming and territory space.

2. Tank setup: Provide a tank with a sandy substrate and plenty of hiding places, such as caves, crevices, and overhangs. These fish form a symbiotic relationship with pistol shrimp, so it's ideal to have a burrowing pistol shrimp species like Alpheus spp. in the tank. Live rock and coral formations can also provide additional hiding spots and perching areas.

3. Water parameters: Maintain stable water conditions. The recommended water temperature for Twinspot Gobies is between 74°F and 82°F (23°C - 28°C). The pH should be within the range of 8.1 to 8.4, and the salinity level (specific gravity) should be maintained between 1.020 and 1.025. Proper filtration, protein skimming, and regular water changes are important for their well-being.

4. Lighting: Twinspot Gobies do not have specific lighting requirements. However, providing moderate lighting that mimics their natural reef environment is generally suitable.

5. Feeding: Twinspot Gobies are carnivorous and feed on small invertebrates and zooplankton in the wild. In an aquarium, they can be fed a diet of high-quality frozen or live foods, such as brine shrimp, mysis shrimp, copepods, and small pieces of fish or squid. It's recommended to provide a varied diet to ensure they receive proper nutrition.

6. Tankmates: Twinspot Gobies are generally peaceful but may become territorial towards their own species or similar-looking fish. They form a symbiotic relationship with pistol shrimp, so it's beneficial to keep them together. Ensure compatibility with other tankmates and avoid aggressive or larger fish that may stress or harm them.

7. Acclimation: Proper acclimation is crucial when introducing a Twinspot Goby to a new aquarium. Slowly drip acclimating the fish to the water parameters of your tank helps reduce stress and increase their chances of acclimating successfully.

Remember that Twinspot Gobies have a specific symbiotic relationship with pistol shrimp, so providing a suitable pistol shrimp species is highly recommended. Proper research and understanding of their needs are important to create a thriving environment for both the fish and the shrimp.
