This goby is very active and adds a lot of personality to my 40-gallon reef tank. It spends most of its time sifting through the sand and digging small burrows. The pink spots stand out well against the background. Easy to care for and doesn’t stress other fish. I’d recommend it to beginners.

Arrived quickly and looks exactly as described. It’s been in my tank for two months and is still very curious and active. The tank size is adequate, and it seems to be adjusting well. A great addition to a reef setup.
