Comments: These are fabulous fish that develop lots of sparkle and, of course, it is very interesting to watch them digging up the gravel on the bottom of the aquarium.
Origin: Eartheaters are members of a very large family of related fish, called Cichlids.
This Eartheater's ancestors lived in the western part of Brazil in South America. But now this Eartheater lives in aquariums all over the world.
Maximum Size: In aquariums males can grow to be about 6.5" long, including their tails, which is a nice size for aquariums: not too big and not too small. Females are a bit smaller than males.
Behaviors: Eartheaters are usually not aggressive fish, but males will quarrel with each other from time to time.
They are more aggressive just before spawning, during spawning, and when protecting their eggs and babies.
They're called Eartheaters, not because they eat earth, but because they lake large mouthfuls of small gravel and sift out food particles to eat.
In this way they help keep the gravel cleaner, which is a big benefit in many aquariums with gravel.
Compatibility: Some recommended tank mates include catfish like Pictus Cats, Plecostomus, and most other fish that are not too aggressive.
Even small fish are not bothered by Eartheaters.

Temperature: Eartheaters live best from about 74 to 82-degrees F., with 78 being perhaps ideal.

Feeding: Premium Fish Food Pellets is the best type of food to feed Eartheaters, and can be fed to them throughout their entire lives. Probably best to feed the smaller size pellets.

Water Conditions: Their ancestors lived in water that is usually soft and rather acidic, but apparently at times the pH and hardness increased in these waters.
So this Eartheater can adapt to most types of tap water, and as usual it's best not to change water chemistry, unless you want to breed them, hatch the eggs, and raise the baby fish.

If water conditions are not kept very fresh, Eartheaters may develop the so-called Hole in the Head Disease.

Aquarium Size: Eartheaters grow fast and soon need to live in an aquarium with at least 80-gallons of water and eventually in an even bigger aquarium, if you have several of them.
Decor: Unlike most aquarium fish, Eartheaters need gravel.
Keep a layer that's shallow enough that they can dig all the way to the bottom.
As they get older and bigger, they will be able to dig deeper.
If the layer of gravel is deeper than they can dig, the gravel will fill with bits of uneaten food and become contaminated.

Live plants are beautiful and improve the water quality, but Eartheaters will usually uproot plants, so aquariums with Eartheaters rarely have live plants.
Here's a way get around that problem. Put the plants in new clean uncontaminated terra-cotta pots with #2 gravel, then top the gravel off with a thin layer of aquarium-safe rocks that are too big for the Eartheaters to move.
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 Eartheaters.
Better is a 120, 150, or 200-gallon aquarium with as many Penguin 350B Filters as will fit across the back.
Eventually one Eartheater will need a large aquarium with filters along the back edge.

Like Oscars, Eartheaters will develop Hole in the Head Disease, if the water conditions deteriorate for several weeks. So dedicated maintenance is a must.

The addition of Lava Rocks will keep nitrates in the ideal range.
