Paratilapia Fish Species and Requirements

Paratilapia fish are a diverse group with over 20 recognized species, each with unique characteristics and requirements.

Some species, like the Paratilapia polyactis, are native to the rivers of Madagascar, while others are found in the lakes and rivers of Africa.

Paratilapia fish are generally small to medium in size, with most species reaching a maximum length of 10-15 cm.

They are a popular choice for aquarium hobbyists due to their vibrant colors and relatively low maintenance requirements.

Paratilapia's relationships to other cichlids remain unclear due to conflicting DNA sequence data from mtDNA16S rRNA and COI.

Phylogenetic analyses have struggled to resolve the genus's placement, with some studies suggesting it occupies a position between African subfamilies like the Ptychochrominae and the Indo-Malagasy clade.

This placement may be correct, with its ancestors separating from other living cichlids in the Mesozoic era.

The Indo-Malagasy clade must have originated before the split of Madagascar from the Indian Plate, which began around 90 million years ago.

Paratilapia's ancestors would have been a distinct lineage by the Turonian, making them a strong candidate for their own subfamily, Paratilapiinae.

The classification of Paratilapia is uncertain, with some species, like P. toddi, possibly not belonging to the genus.

There are two recognized species in the Paratilapia genus: Paratilapia polleni and Paratilapia toddi. However, it's worth noting that Paratilapia toddi is unlikely to belong in this genus.

Paratilapia polleni is a laterally compressed, full-bodied fish that resembles a perch-type fish in shape. Males in captivity develop a nuchal hump and have a bright yellow eye, while females are usually half the length of males and have a more rounded head shape.

Here's a brief comparison of the two species:

The small-spot variant of Paratilapia polleni is actually a distinct species, and has been given the name Paratilapia bleekeri in honor of the person who described P. polleni.

The Paratilapia genus is home to two recognized species. One of them is Paratilapia polleni, which was first described by Bleeker in 1868.

Paratilapia polleni is a well-documented species, but there's some uncertainty surrounding Paratilapia toddi. It was described by Boulenger in 1905, but it's unlikely to actually belong in this genus.

Here's a list of the recognized species in the Paratilapia genus:

P. polleni is a laterally compressed, full-bodied fish, resembling a perch-type fish in shape. Most cichlids share this characteristic, which is why they're classified as perciformes - 'perch-like'.

Males develop a nuchal hump, a layer of fat above the eyes, in captivity. This hump is less pronounced than in other similar African cichlids.

Adult and subadult dominant P. polleni individuals are jet black in color, with brilliant iridescent spots that shift from golden to blue depending on movement and light. These spots are a striking feature of the fish.

The eye is a bright yellow, adding to the fish's vibrant appearance. Females are usually half the length of males, making sexing individuals easier as they mature.

Males tend to have longer and sharper pelvic fins, a more rounded head shape, and straighter edges on the dorsal and anal fins. These characteristics can be used to distinguish males from females.

Females are said to be more beautiful in their coloration patterning, despite being smaller. This is a notable observation among aquarists.

In one notable case, a tropical fish wholesaler from New Jersey observed distinct differences in behavior, size, and fright coloration between two 'spot' variations of the fish.

Paratilapia is a versatile fish that can thrive in a variety of environments. To keep your Paratilapia happy and healthy, aim for a water temperature between 62-82°F (17-28°C), with a target range of 72-80°F.

The pH level should be maintained between 6.5-8.0. This pH range is crucial for the fish's well-being.

Hardness should be kept between 8-25°H. This will help create a stable environment for your Paratilapia.

Paratilapia is an adaptable fish that can survive in different water conditions, but providing a stable environment will help it thrive.

To keep your Paratilapia polleni thriving, start by providing a suitable environment. The temperature in the aquarium should be between 72-80°F, and the pH level should be between 6.5-8.0.

P. polleni is a hardy fish that can tolerate temperature and pH fluctuations, making it a great choice for aquarists. They are also relatively easy to care for, as long as you provide them with the right food and tankmates.

To feed your P. polleni, offer them a variety of commercial fish foods, such as flakes, pellets, frozen, and live foods. They are highly proficient at capturing live foods, so be prepared to provide them with a diverse diet.

One of the most interesting things about P. polleni is their ability to recognize and approach their owner. They can even be trained to eat from the hand, which is a great way to bond with your fish.

However, P. polleni can be aggressive towards conspecifics, especially if a male/female bond develops. To avoid this, it's best to keep only one or two fully colored individuals in the aquarium, and separate them from non-dominant and sub-dominant individuals.

Here are some tankmate guidelines to keep in mind:

Remember, P. polleni can be prone to aggression, especially as they mature. So, be sure to monitor their behavior and separate them from tankmates if necessary.

Paratilapia reproduction is a fascinating process that requires careful consideration. Bi-parental substrate spawners, Paratilapia fish will usually pair off naturally if given the chance, often holding individual territories that can span over 3 feet of the aquarium length.

To encourage pairing, it's recommended to purchase a group of young fish and let them form their own pairings. A tank length of at least 48″, preferably 60″ or more, is ideal for this process.

As courtship begins, the male will take on intense dark coloration and display to his partner, often including the impressive "headstanding" display. The female will also undergo a similar patterning just before spawning.

The female will lay her eggs in a large pit in the substrate, which can be on the substrate itself, on a piece of wood, or even on the roots of plants after removing the substrate around them. Up to 1000 eggs can be laid, forming long 'strings' of spawn.

The eggs have a long sticky filament attached to them, which helps them attach to other eggs, forming these 'strings'. The female will tend and guard the brood while the male guards the territory against intruders.

After 48 hours, the eggs will hatch, and the fry will remain in the spawning site for the initial phase of life. They'll become free swimming after 6-7 days and can accept brine shrimp nauplii, microworm, and powdered dry foods from this point.

If you choose to remove the fry to a separate aquarium, you can do so now. However, if you leave them with the parents, both fish will defend the brood, and this care can last for up to 3-4 weeks after the fry become free swimming.
