The Purple Firefish Goby is a beautiful addition to my 30-gallon reef tank. It moves gracefully and doesn’t bother the corals. Easy to set up and very active. I’m happy with the color and behavior.

This fish arrived healthy and vibrant. It’s peaceful and stays near the back of the tank. I didn’t have to worry about aggression or compatibility issues. A great choice for a small reef setup.
Sonia Langdon –
The fish looks exactly as described. It’s a nice color and stays active. A bit shy at first, but settles in well. I’d recommend it for beginners with a 24-gallon tank or larger.
