Overview

The Mono Sebae is also known as the African Moony and comes from the estuaries and mangroves of the waters of West Africa. It is diamond shaped with a larger anal fin than the Mono Argentus. The Mono Sebae is silver with a black line covering the eyes and a line from the tip of the dorsal fin to the tip of the anal fin.

The Mono Sebae grows very large and requires an aquarium of at least 125 gallons. The smaller specimens can be kept in freshwater, but as they grow and mature, the water should gradually be converted to a higher salinity. A substrate consisting of aragonite sand or gravel is preferred. Provide plants and rocks that thrive in brackish water.

It is known that the Mono Sebae spawns in the saltwater of the ocean, but the difference between the sexes and their breeding habits are unknown. Gradual change from brackish to saltwater will maximize the coloration and the health of the fish as they become older.

In the wild, the Mono Sebae eats large amounts of vegetable matter. Provide them with dried seaweed, lettuce, brine shrimp, and a quality flake food.

Approximate Purchase Size: 1-1/2" to 2-1/2"

Customer Testimonials

Tristan M Anthem , AZ
I absolutely love this fish. I purchased a school of these and they create so much movement throughout the tank. They have not bothered any of my other angelfish or smaller fish in my tank. Although I have notice that there are bite marks in my live plants so I would suggest artificial or non planted tank when housing them. I’m very happy with these fish and they are definitely one of my top 3 favorites.
