Comments: This is an awesome Cichlid species.
Origin: The ancestors of the this fish lived from Honduras to Costa Rico in eastern Central America. But now they live in aquariums all over the world.
Maximum Size: In aquariums males are said by others to grow to be 24" long but about 12" long, including their tails is the biggest we've seen, and females are smaller.
Behaviors: Managuensis are usually very aggressive, and they are territorial and even more aggressive when spawning.
Compatibility: Small Managuensis are OK with other fish of about the same size, but as they grow bigger, they'll eat fish that are small enough to fit into their mouths, and as Cichlids they can be hard on less aggressive fish.
Good tankmates are Pictus Catfish, Plecostomus Catfish, Anostomus, Leporinus, and Silver Dollars that are too big to be eaten.

Temperature: Managuensis live best from about 72 to 80-degrees F. with 75 to 78 being perhaps ideal.

Feeding: Premium Fish Food Pellets is the best food for these Cichlids to eat.
It's best to feed them small pellets when they're small, then gradually increase the size of the pellets as they grow larger.

Water Conditions: 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.

Aquarium Size: Managuensis will eventually need to live in an aquarium with at least 80-gallons of water, and bigger is better for this huge species.
Decor: They don't 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.
Live plants are beautiful and improve the water quality, but this fish will usually dig plants up, so most aquariums with Managuensis do not have live plants.
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 the minimum set up for large Managuensis.
Better is a 120, 150, or 200-gallon aquarium with as many Penguin 350B Filters as will fit across the back.

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: Managuensis 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 breed to produce the next generation of fish for your aquarium.
Gender: It's nearly impossible to tell males from females just by looking at them, when they're young, but as they mature, the males will grow larger than the females.
But this species occurs over a wide geographical area, so there are probably variations in their colors and patterns.
