The male goby has developed bright red markings on its lips and back. It’s very lively and adds a lot of visual interest. I didn’t expect such vivid coloration in a dwarf goby.

Great addition to my aquarium. The fish is active and stays in the current zones. The coloration is more pronounced after a few weeks. I’m happy with the purchase and the shipping speed.
