We stock and ship fish that are the ideal size to ship. Not so small that they will not do well when shipped. Yet not so big that they will have trouble adjusting to a new home.

The fish in almost all of our pictures were young fish like the ones we ship that we raised up, and you can too!

Comments: These are fabulous fish. The males are dark with bright spangles.

Origin: The ancestors of the Black Diamond Cichlid lived only in Madagascar, which is an island off the east coast of Africa. But now they live in aquariums all over the world. 

Maximum Size: In aquariums, males are said to grow to be about 12" long, but so far we haven't seen one bigger than about 11" long, including their tails, which is a very large for most aquariums. Females are smaller and remain gray without the dark pattern with light spots shown on the males.

Behaviors: Black Diamond Cichlids are usually rather aggressive fish, and sometimes eat their tank mates if they can fit them in their mouths, as they mature.

Compatibility: Some recommended tank mates include mild tempered Mbunas like the Lemon Yellow Mbuna, and Synodontis Catfish, also Cichlids from Lake Victoria, but probably not Cichlids from Lake Tanganyika. But be careful, they will eat anything that can fit in their mouth, so you may want tank mates more suitable to their size. Click here for more about Synodontis Catfish. Click here to read more about compatible groups of pet fish.

Temperature: they 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 the best food for Cichlids to eat. It would be best to feed them small pellets when young, then gradually increase the size until they are mature. In Madagascar the Black Diamond Cichlid eat small fish but do not require live fish when living in an aquarium. Click here to learn more about and shop online for premium fish foods.

Water Conditions: Madagascar has hard alkaline water and that's best for all the fish, who's ancestors lived there. But these fish can adapt to most types of water, and so as usual it's best not to try to change the pH or hardness. Click here for a lot more information about aquarium water conditions.

Aquarium Size: Black Diamond Cichlids will eventually need to live in an aquarium with at least 80-gallons of water. Perhaps best kept alone or with a few Synodontis Catfish. Eventually one of these fish may need a huge aquarium.

Decor: Black Diamond Cichlids 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 this fish will usually rip plants up, so most aquariums with Black Diamond Cichlid do not have live plants. They like a thin layer of medium size gravel about the size of rice mixed with a few aquarium-safe rocks.

Aquarium Filter: Bio-Wheel Filters are highly recommended. Most 80-gallon aquariums have room along the back for two Penguin 350B Filters, and this is sort of the minimum set up for Black Diamond Cichlid. Better is a 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: Black Diamond Cichlids can live for several years. Keep the water conditions excellent and feed them premium foods, and they'll most likely live for many years, and they may breed to produce the next generation of fish for your aquarium.

Gender: It's difficult to tell males from females, when they're very small, but easy when they are mature, because the males change from gray to be very dark with light specks.

Breeding: the female lays eggs, a male fertilizes the eggs, and both parents guard the eggs for a few days until they hatch. The fry soon become miniature versions of their mother and very cute! Click here to read more about breeding mouthbrooders. the aquarium. Click here for a lot more about breeding various tropical fish in aquariums.

Popularity: The Black Diamond Cichlids from Madagascar has been a rather popular aquarium fish. The males have a very unique pattern.

Names: Their scientific name is Paratilapia polleni

Variations: There may be two variations with large or small spangles on the large males.

We hope you've enjoyed reading these comments.
