Humpnose Big Eye Bream

(Monotaxis grandoculis)

Provide an aquarium with plenty of rockwork, cracks, crevices and caves for hiding. Breams also require wide open swim areas and a deep sand bed. They will sift through the sand looking for prey. Breams are not reef safe and will eat any fish or invertebrate they can fit in their mouth. Provide a diet of meaty based foods three times a day. Breams may not eat prepared foods when first acclimated, try feeding enriched live adult Brine Shrimp or Black Worms. Juveniles are colorful but as the fish matures their coloration will fade. Bream should be housed with other peaceful tank mates. Keep only one per aquarium and provide a tight fitting lid as they may jump.

Humpnose Big Eye Bream are also sometimes known as the Bigeye Monocle Bream. In the aquarium trade, bigeye monocle breams are not commonly seen due to their relatively large size and specific dietary requirements. They are primarily caught for commercial and subsistence fishing. Bigeye monocle breams have a laterally compressed body with a silvery coloration and a dark stripe running horizontally along their sides. They have a large, prominent eye, and a small mouth with sharp teeth. They can grow up to 20 inches in length.

We recommend a minimum aquarium size of 360 gallons or larger for this species.
