When the fish is in its breeding plumage, its red body turns a vivid purple. The fish’s body is covered in dots that are turquoise, with a black spot in the center.

Size

15 cm is the maximum standard length.

Behavior and Compatibility

A territorial species that, once spawning season arrives, turns extremely aggressive. It can be kept in a large enough tank with other African cichlids like the Lionhead Cichlid (Steatocranus casuarius) or with larger tetras of the Alestidae family* like Congo tetras, Synodontis catfish, and Loricariidae.

Fish are best kept in pairs, but if you just buy a pair, the weaker fish will usually be killed. To let the young fish form a pair on their own, you will need to purchase a group of them.

* The family of ray-finned fish belonging to the order Characiniformes is called African tetras. unique to Africa. There are roughly 119 species and 18 genera in this family. Phenacogrammus interruptus and the genus Hydrocynus are the most well-known examples.

Aquarium

The aquarium measures 100*30*30 cm and holds 100 liters.

To help deter aggression and provide shelter, provide a large aquarium with as many hiding spots and shelters as you can. Driftwood, different grottoes that resemble caves, clay flowerpots, and places with dense vegetation can all be used to achieve this. All plants, though, should be deeply rooted or in pots because Chromis bonnet are diggers.

Water parameters:

In the range of 22 to 28 °C pH range: 6.0–7.8 Hardness: 4–18 ° DH

The purity and oxygenation of the water are critical factors. frequent changes of the water. It is preferable to use an external filter given the fish’s diet and digging habit.

Feeding

Sexual dimorphism

Difficult to tell apart. observe on a fish’s tail fin. The middle of the fin on males is covered in a blue mesh pattern. Additionally, male adults grow pointed dorsal fins. It is believed that females are smaller and have rounder bellies.

Reproduction

Relatively easy. Basic breeders. It is difficult to select a pair of adult Chromis, so it is recommended to purchase 5 or 6 young fish, allowing the pair to form naturally. However, even this may take some time. The fish should be kept in a species aquarium, where conditions are created as suggested above, with the addition of a few large rocks to act as spawning areas, and a good varied diet is provided. A tank of about 100 cm will be a suitable spawning tank. The water should be slightly soft and acidic with a pH of about 6.5-7.0 and a temperature of 25-28 ° C. Once a pair has formed, the other fish should be removed, as they may be killed. This pair will now remain together for life.

When a pair is ready, the color becomes more intense and has an amazing effect. Remove any additional fish from the tank right away as they will probably perish. The fish will even attack your hand at this point! They will select and thoroughly clean a spawning site on a flat rock (usually an area at a slight angle), the side of the pot, or even the tank’s glass. If the female isn’t ready, the male will pursue her until she dies because he is a very active and aggressive chaser.

Similar to many other cichlid species, a female lays a row of eggs before moving on so that the male can take her place and fertilize them. This method can fertilize up to 600 eggs. In roughly 48 hours, the larvae hatch, and the male guards the clutch during this time. On occasion, the parents take turns being the parents. Around the spawning site, the pair will also excavate a number of shallow holes or depressions in the substrate at this time.

The female moves the entire brood to one of these holes as soon as the larvae hatch, which takes around 72 hours. Before they can swim unassisted, they will typically need to be moved a few more times, usually within a day or two. They can now be given microworms or brine shrimp nauplii. When the fry reach about 1 cm in length, or after about a month of care from the parents, it is time to remove them because the parents might start spawning again.

Lifespan: roughly five years.
