Rachel White –
Added the Firefish Goby to my 24-gallon reef tank and it has been active and colorful since day one. The red and white pattern stands out well in the tank. Very peaceful and doesn’t bother other fish. Perfect for a beginner aquarist looking for a lively but calm addition.
Dylan Abraham –
This goby is a real eye-catcher. It moves gracefully and stays in the middle of the tank. I didn’t expect it to be so active, but it’s not aggressive. Works well with corals and other small fish. Easy to keep and very hard to miss.
Una Jackson –
It arrived healthy and has been thriving in my tank. The size is smaller than expected, but it’s still very vibrant. I like how it doesn’t chase or stress other fish. A great choice for a small reef setup.
