I added a Bluespotted Watchman Goby to my 30-gallon reef tank and it has been thriving. It’s active but not aggressive and doesn’t bother the corals. Easy to care for and looks great in the tank. Perfect for a beginner aquarist.

This fish is a great addition to a small reef tank. It’s colorful, curious, and stays near the sand bed. I’ve kept it for three months and it’s still doing well.
