Fish Data : White-Tailed Brichardi Cichlid




The White Tailed Brichardi Neolamprologus gracilis is truly a graceful fish. They have slender bodies and delicate colors. Their lyre shaped tail is tipped in white and both the male and female develop beautiful long streaming filaments on their fins. In the wild some specimens have been seen with flowing filaments equal in length to their body. They are affectionately called the Graceful Lamprologus as well as Gracilis Cichlid and Blue-tail Brichardi.

This beautiful fish makes an elegant addition to the aquarium. It is easy to care for as long as regular water changes are done. It is a relatively small cichlid, reaching only about 3 1/2 inches (9 cm) in length, so it doesn't require a large aquarium. A minimum 10 gallon tank will work for one or two individuals and they will adapt to a wide range of water conditions and eat a wide variety of aquarium foods. With its color, form and adaptability, it is a great choice for both the beginner and advance aquarist.

The Graceful Lamprologus have a less aggressive demeanor, which makes them some of the easier Lake Tanganyika cichlids to keep in a community setting. They can be kept in pairs or singly, or in harems that form a group of 6 or more. They are generally aggressive toward those of the same species, but may tolerate others of their own genus. In the wild this cichlid has been seen cohabiting with its close relative the Fairy Cichlid Neolamprologus brichardi. It's not suggested keeping them together in the aquarium however, since hybrids can be formed.

They are not as aggressive as many other cichlids so may be kept with other similar tempered types of Lake Tanganyika cichlids. The tank just needs to be large enough to support the number of fish being kept and have plenty of rockwork for each species to have their own territories. hey are best kept in a species tank, or a group of these fish can be kept in a good sized aquarium with other similar types of Lamprologine Shell-dwellers. Other good tankmates are a large school of Herring cichlids of the Cyprichromis genus like the Sardine Cichlid Cyprichromis leptosoma, as well as Goby Cichlids, Julidochromis species, and Tropheus species. In fact this grouping is very attractive in a 55 gallon tank, as all have different swimming levels and breeding activities.

This pretty cichlid is not shy about swimming out in the open. They will breed readily and are easy to feed as well. But they do like an aquarium with lots of rock formations creating caves along with shells to provide areas of retreat and for spawning. A sandy substrate is best. Though they are not avid diggers, they may dig out spawning territories around decor. They won't harm plants, and including them will help the fry survive.

The White-Tailed Brichardi is a graceful elongated fish with a continuous dorsal fin. The tail fin is lyre shaped and they develop long flowing filaments on all unpaired fins. These fish are in a category called "fairy" cichlids due to their long flowing fins. They are relatively small, only reaching up to about 3 1/2 inches (9 cm) in length. TheNeolamprologus genus will generally live 8 - 10 years with proper care.
They are mostly white colored with a slender white to light blue line under the eye. The iris of the eye is split between blue and white. Their caudal fin is tipped in white and is what earns them their common name. Unlike the Fairy Cichlid Neolamprologus brichardi, they lack the dark markings on their face.
All cichlids share a common feature that some saltwater fish such as wrasses and parrotfish have and that is a well-developed pharyngeal set of teeth that are in the throat, along with their regular teeth. Cichlids have spiny rays in the back parts of the anal, dorsal, pectoral, and pelvic fins to help discourage predators. The front part of these fins are soft and perfect for precise positions and effortless movements in the water as opposed to fast swimming.

Cichlids have one nostril on each side while other fish have 2 sets. To sense "smells" in the water, they suck water in and expel the water right back out after being "sampled" for a short or longer time, depending on how much the cichlid needs to "smell" the water. This feature is shared by saltwater damselfish and cichlids are thought to be closely related.

These fish make a great choice for both the beginner and advance aquarist. They are moderately easy to care for as long as the tank is properly maintained and they have the right tank mates. The aquarium needs regular, small water changes. They are fairly peaceful, making good inhabitants for the community cichlid tank. They will eat a wide variety of aquarium foods and will readily breed.

The White-Tailed Brichardi cichlids are omnivores that are primarily planktivorous. In the wild they bulk of their diet is swarms of open water plankton, but they will also pick at aufwuchs, a loose stringy algae which contains small crustacean and other micro-organisms. In the aquarium they will generally eat all kinds of live, fresh, and flake foods.

To keep a good balance give them a high quality flake food or pellet everyday. Regularly supplement these foods with proteins like brine shrimp (either live or frozen) or daphnia. They can be fed mysis shrimp, earthworm flake, frozen adult brine shrimp and once in a while spirulina. Other special food for carnivorous Lake Tanganyika cichlids are acceptable.

It is suggested that you do not feed live foods and tubifex worms due to possible diseases and pathogens that may be transferred to your fish. Feed 2 to 5 small pinches of food a day in smaller amounts instead of a large quantity once a day. A one-day-a-week 'fast' can also be beneficial. All fish benefit from vitamins and supplements added to their foods.

Do water changes of 10% to 15% a week, or more frequently depending on the nitrite/ammonia levels and stocking numbers. The Lake Tanganyika cichlids cannot handle large water changes very well unless the new water chemistry closely matches the water they are in. If a large water change is needed, changing 15% every couple of days should bring water back to normal. This inability to tolerate large water changes is due to Lake Tanganyika being very deep and the water tends to stay stable.

The White-Tailed Brichardi will swim mostly in the middle and bottom areas of the aquarium. A minimum 10 gallon tank for pair is suggested, with a 20 gallon for a group and 55 gallons or more for a community type tank. They do fine in either freshwater or brackish freshwater but need good water movement along with very strong and efficient filtration. Lake Tanganyika is a very oxygen rich lake so bubblers need to be going day and night, even if there are plants. Regularly check nitrates and ph, nitrates should be no more than 25 ppm and a pH less than 7 is not tolerated. In addition keep an eye on total hardness and carbonate hardness. Avoid overfeeding and overstocking.

Lake Tanganyika is the second to largest lake in the world, thus contributing to a low fluctuation in temperature and pH. All Tanganyika cichlids need stable temperatures kept within acceptable limits and lots of oxygen to survive. Temperatures under 72° F and over 86° F for too long is not tolerated by many of these fish. When treating for ich, a few days at 86° F is acceptable. The lake is also consistently alkaline with a pH of around 9, and very hard at about 12 - 14° dGH. In the aquarium most Tanganyika cichlids are fairly adaptable as long as conditions are close to these ideal ranges. Most important is that their water chemistry doesn't change much over time. The water needs to be well buffered and maintained with small, regular water changes.

Salt is sometimes used as a buffering agent to increase the water's carbonate hardness. An alternative buffering approach is to use a chemical filtration method, where they water passes through layers of crushed coral or coral sand.  Interestingly, Tanganyikan cichlids also need iodine for the thyroid to function properly to regulate growth and development, and which can be achieved by adding iodized table salt to the water. Although rift lake cichlids need hard alkaline water they are not found in brackish waters. This cichlid has some salt tolerance so can be kept in slightly brackish water conditions. However it not suited to a full brackish water tank. It can tolerate a salinity that is about 10% of a normal saltwater tank, a specific gravity of less than 1.0002.

Provide a sandy or very small sized gravel substrate. Sand used for salt water tanks can help keep the pH up as well as the addition of crushed coral. Crushed coral and aragonite sands do tend to dissolve easier than salts. They should have rock formations creating caves along with shells for spawning. Include some plants to help the fry survive. A good plant arrangement can have Cryptocoryne species in the foreground, in the middle ground useSwordplants that are the larger variety, and the very back can have Water Fern. For a different or varied look you can plant on the porous rock with such species as Anubias and Java Fern.

The White-Tailed Brichardi has been bred in captivity and will readily spawn. Purchase 6 or more juveniles and allow them to pair up. After a pair or small groups of 3 or more has formed, remove the remaining White-Tailed Brichardi since the newly established pair will attack the others if they enter their territory. If left in the tank, these "exiled" fish may eventually be killed if they persist in going into the established territory.

Provide a pair with at least 2 or more shells, as this is their preferred spawning container. Females deposit their eggs in the shell and the male will then fertilize them. The parents both share the duty of guarding the eggs and fry. They will also allow older siblings to care for new spawns while they start a new generation. Siblings at only 1/4 of an inch long will attack intruding fish ten times their own size. It is quite amusing to watch a tiny fry make a large fish back away.

Fry can be fed de-encapsulated brine shrimp as well as crushed dry foods, although hatched or frozen baby artemia, and/or artemia/brine replacement foods are needed due to their high lipid and protein level. These levels contribute to improved survival rates and increased growth rates. Of course in a community tank, the survival rate of the fry may drop. It is a good idea to remove plecostomos and loaches as they will eat the babies and eggs at night.
