Received the Cobalt Blue Dwarf Goby and it’s been thriving in my 10-gallon nano tank. The male has developed a striking blue coloration after a few weeks. It’s peaceful and doesn’t bother the shrimp. Easy to care for and a beautiful addition to the tank.

The fish arrived healthy and active. The blue coloration is quite vivid, especially in the male. I’ve kept it with cherry shrimp and they coexist well. Water parameters are stable and it seems to adapt quickly.
