Julia Ball –
Easy to care for and very peaceful in my 50-gallon tank. It’s been living with other reef fish without any issues. Looks vibrant and active. Perfect for a beginner aquarist.
Sally Carr –
I added this goby to my reef tank and it has adapted well. It doesn’t chase other fish and stays in one area. Good size for a small tank with plenty of space.
Jan Peters –
The goby is active and colorful. I’ve had it for three months and it’s still healthy. No aggression, and it blends well with the coral setup.
