What is substrate brooding?
The substrate-brooding African cichlid Neolamprologus mondabu is known to engage in fin-digging for its own feeding [23]. This cichlid is endemic to Lake Tanganyika in East Africa, and preferentially inhabits sandy substrates in rocky areas, where it feeds on benthic animals [24].
What substrate do cichlids prefer?
sand substrate
For cichlids, a sand substrate is considered the best. That’s because cichlids love to dig and move the sand around, and they exhibit the same behavior in nature which serves many purposes, such as scavenging for food or making nests for laying eggs. The pinnacle of sands is aragonite sand.
Can cichlids live with gravel substrate?
Substrate size is an important consideration. Your African cichlids will love to dig into the tank’s floor. Medium or small-grained gravels and sands offer these fish an opportunity to stay active and stimulated. It also mimics their natural habitat more closely than larger products can.
Do cichlids like gravel or sand?
Tank Size: Cichlids grow to a large size, so the bigger the tank the better. Substrate: The bottom of the environment should be sand. Some Cichlid species will ingest a small amount to aid in digestion, while others use the sand bed to build their nest. Larger Cichlids like Oscars are fine with gravel.

Females will spawn approximately every 6 weeks if well fed. Most females will eat while incubating, but all usually lose weight during that time. It is important to feed a variety of high quality and palatable foods to keep your breeders in condition.
How many days do cichlids hold eggs?
21 to 36 days
African cichlids, which are maternal mouthbrooders, are an example of fish that continue to protect their young even after the eggs have hatched. Female African cichlids hold eggs in their mouths for 21 to 36 days. During this time, the female does not eat, leaving no opportunity for an egg to escape.

The cysts look like grains of salt on the fish. They may cause African cichlids to rub themselves on rocks to try and dislodge the parasites.
Why is my cichlid moving the gravel?
Cichlids often move around the rocks in a fish tank because they are trying to hide from the bigger, meaner fish that are chasing them. Male cichlids stake out territories, and once they have their favorite area they will chase all other fish away.
