Comments: This is a fabulous fish with vibrant colors and patterns.

Origin: Ndumbi are Mbunas, which is a large family of Cichlid fish that originally lived only in Lake Malawi in East Africa.

The Ndumbi Mbunas live on the Ndumbe Reef, which is in Tanzania. But now this species lives in aquariums all over the world. There are many other species of Mbunas for sale in this store.

Maximum Size: In aquariums a Ndumbi can grow to be about 4" long, including their tails, which is a very nice size for aquariums.

Behaviors: Ndumbi are usually rather aggressive fish and from time to time males have long energetic fights.

Compatibility: Some recommended tank mates include, other Mbuna species and Synodontis Catfish. Click here for more about Synodontis Catfish. Click here to read more about compatible groups of pet fish.

Temperature: Mbunas live best from about 75 to 80-degrees F. with 78 being perhaps ideal. Click here to learn about aquarium temperature, aquarium thermometers, and aquarium heaters.

Feeding: Premium Fish Food Pellets is best to feed to Mbunas. Smaller sized pellets when the fish are small and young, and larger sized pellets when the fish grow to be bigger, is the ideal food for these fish. Click here to learn more about and shop online for premium fish foods.

Water Conditions: Lake Malawi has hard alkaline water, which is best for all the fish, whose ancestors lived there.

ut these fish can adapt to most types of water, and so as usual it's best not to try to change the pH or alkalinity. Click here for a lot more information about aquarium water conditions.

Aquarium Size: Mbunas, like this Ndumbi, will eventually need to live in an aquarium with at least 80-gallons of water.

Each Mbuna will need at least 5-gallons of water, and Mbunas live best in an aquarium with at least 15-other Mbunas of about the same size.

Decor: Mbunas do not need gravel, and a layer of gravel more than 1/4" thick will usually fill with bits of uneaten food that will contaminate the water. Click here for more about aquarium gravel.

Live plants are beautiful and improve the water quality, but Mbunas will usually dig plants up, so most Mbuna aquariums do not have live plants, Mbunas love rocks and rocky caves.

Aquarium Filter: Bio-Wheel Filters are highly recommended. Most 80-gallon aquariums have room along the back for at least two Penguin 350B Filters, and this is sort of a minimal Mbuna set up.

Better is a 100, 120, 150, or 200-gallon aquarium with as many Penguin 350B Filters as will fit across the back. Click here to learn more about aquarium filters.

The addition of Lava Rocks will keep nitrates in the ideal range. Click here to learn more about using Lava Rocks in aquariums.

Life Span: Mbunas can live for several years. Keep the water conditions excellent and feed them premium foods, and they will most likely breed to produce the next generation of fish for your aquarium.

Gender: It's difficult to tell males from females, when they're  small, but easy when they are mature, because the males change color and become a very colorful, while the females stay more gray.

Breeding: Ndumbi and all Mbunas are mouthbrooders. A female lays eggs, a male fertilizes the eggs, and the female picks up the eggs in her mouth.

She'll brood them for about 3-weeks, then release them in the aquarium. They are miniature versions of their mother and very cute!

Popularity: Ndumbi and other Mbunas from Lake Malawi are popular aquarium fish.

Names: The scientific name for Ndumbi is Pseudotropheus perspicax.
