The Bicolor Foxface is a striking addition to my reef tank. Its color pattern is unique and eye-catching. I’ve kept it in a 150-gallon tank with other fish, and it’s very peaceful. It eats algae and vegetables regularly, which helps keep the tank clean. I’ve not had any coral damage, likely due to consistent feeding.

This fish looks beautiful with its dark and yellow body split. It’s calm and doesn’t bother my corals as long as I feed it daily. I noticed it raises its dorsal spines when startled, which is a good defense mechanism. Feeding it fresh veggies and algae keeps it healthy.

The fish is visually appealing, but I had to adjust feeding frequency to prevent it from nibbling on soft corals. I now feed it twice a day. It’s not aggressive, but it does require a large tank and consistent care.
