Easy to care for and very peaceful in my 10-gallon tank. It blends well with other fish and doesn’t cause any stress. The yellow stripes are vibrant and stand out nicely. Perfect for beginners.
Victoria Stewart –
I’ve had this fish for three months now and it’s still active and healthy. It doesn’t eat much and doesn’t bother other tank mates. A good choice for a small reef setup.
Dylan Hodges –
The fish arrived quickly and looks exactly as described. It’s calm and stays near the back of the tank. I’m happy with the beginner-friendly nature and peaceful behavior.
