Nutrition and feeding
Omnivorous fish in nature feed on invertebrates and organic debris.
In the aquarium, they are not picky and accept most of the available food. A diet rich in live foods such as artemia, daphnia, etc. will ensure their good condition.
They require a minimum length of 80 cm of the aquarium (preferably larger). The tank should have a dark substrate, a few flat stones, roots, and floating plants to provide some shade.
Such decoration will best reflect their natural environment. They do not like too strong water current and bright lighting. Sensitive to water pollution and require regular water changes. Outside the breeding period, very gentle, shy and fearful fish. It is not recommended to keep it with other cichlids except for scalars, discus and small South American cichlids.
A bit of boldness will give them the company of a shoal of small, gentle benthic fish, tetras, razbor, etc. An ideal companion will be microorganisms sticking to the upper parts of the water, eg Beckford, edged .
Monogamous species, easy to reproduce. On a well-balanced diet, they do not need any additional encouragement to spawn. It’s best to start by buying young fish, wait for the steam to form naturally, and then separate it.
The female lays eggs on hard, flat surfaces, it can be, for example, a flat stone, a root, a wide leaf or an aquarium glass. Young or inexperienced couples may eat the fry of the first litters , especially when they feel threatened or frightened. In the act of spawning, the female lays the eggs in rows and they are then fertilized by the male. An adult female is able to lay about 300-400 eggs, which she takes care of. The male is responsible for patrolling and protecting the territory.
When breeding maroni acars in a general aquarium, if we want to raise more fry, it is recommended to catch the stock or transfer the eggs to another tank. Hatching takes place within 3-5 days. The fry are easy to feed and as soon as they begin to swim independently, they can eat good quality powdered dry food, brine shrimp larvae, micro nematodes, etc. Parents look after their offspring for up to 6 months . Young fish, after reaching approx.
6 cm, become sexually mature, begin to pair up and embrace the territories.
