The Mustard Guttatus is vibrant and active in my 100-gallon reef tank. It doesn’t damage corals and adds visual interest. I’ve had it for six months and it’s thriving. Only needs occasional feeding and is easy to spot in the tank.
Amelia Gibson –
Great color and movement. It’s not overly aggressive, but it does defend its feeding area. I keep it with other peaceful fish and it’s doing well. Tank size was 80 gallons, which felt sufficient.

This fish has become a centerpiece in my tank. It’s active, colorful, and doesn’t harm the reef. I appreciate the clear size and display height info. Easy to care for once the tank is stable.
