Fairy Cichlid / Princess of Burundi

Geographic Origin and Biotope: Endemic to the rocky shorelines of Lake Tanganyika (notably around the Burundi coast). They congregate heavily along massive vertical underwater cliffs and steep rocky rubble fields, rarely straying from the complex safety of the dark rock crevices.

Taxonomy and Morphology: A highly elongated, slender rock-dwelling cichlid. Maxing out around 9-10 cm (3.5 - 4 inches). Its alternative name, the 'Fairy Cichlid', perfectly describes its fins: the tail is deeply forked (lyretail), and every single point on its dorsal, anal, and tail fins elongates into spectacular, graceful, long white thread-like filaments that trail beautifully behind it like a bride's train. Its mouth is pointed and upturned for grabbing zooplankton from the water column.

Social Behavior: TRUE EUSOCIALITY. They are the 'Ants or Wolves' of the aquarium. The most fascinating family dynamic of any freshwater fish. When an Alpha male and female pair off and breed, the resulting babies grow up. INSTEAD of the parents banishing them (like 99% of other cichlids), the older children stay at home and become 'Helpers'. When the parents breed again, this massive army of older siblings aggressively guards the cave and cares for the new fry. The tank rapidly turns into a massive, impenetrable, multi-generational fortress of dozens of fish working perfectly together to slaughter any intruders.

Coloration and Sexual Dimorphism: Delicate, pale, and incredibly refined compared to the loud neon colors of other African lakes. The body is a smooth, soft, dusty sand/cream color, often glowing with a pale rose or blush-pink hue under good lighting. The eyes are an intense, glowing icy-blue. The unmistakable signature is the 'Facial Mask': a dark, sharp 'V' or 'Y' shaped chevron marking located right behind the eye on the gill cover (operculum), accented with a brilliant yellow dash. Males and females look totally identical to the naked eye. In very old dominant males, the tail filaments can grow phenomenally long, trailing inches behind them.

Tank Setup: A 80-100 cm (30-40 inch / 30-40 gallon) tank is the minimum to handle a booming dynasty. THE ROCK WALL IS MANDATORY. You must stack dozens of large slate, lava, or limestone rocks to the very top of the water line to create massive, dark, interconnected caves. Leave the entire front of the tank as open swimming space (with fine sand). They will patrol the open water but instantly bolt backward into the rock wall if scared.

Feeding: Micro-Predator / Zooplankton feeder. In the wild, they hover near their rocks and snap tiny bugs out of the water column. Do not feed them large carnivore pellets; their mouths are too small. Feed ultra-premium, finely crushed flakes or micro-pellets. To encourage massive breeding and spectacular fin growth, heavily supplement their diet with frozen or live Baby Brine Shrimp (nauplii), Daphnia, and Cyclops. They will frenzy and coordinate feeding runs as a family.

Water Quality: African Rift Lake chemistry is required. Flawless, hard, highly alkaline water. pH 8.0-9.0. High GH and KH (use crushed coral). Temp 24-27°C (75-80°F). They are built like tanks and are incredibly resistant to disease, but if nitrates spike above 40ppm due to massive overpopulation, the colony will suddenly crash and die off rapidly. Strong oxygenation is essential.

Compatibility: THE 'SPECIES TANK' IS THE ONLY WAY. Never throw a pair of Brichardi into a random 'Mixed African Cichlid' tank (Mbunas and Peacocks will stress them, or the Brichardi army will murder the other fish). Keep them exclusively by themselves (just start with 5 or 6 juveniles and wait for them to form a colony). If you must mix them in huge tanks (150cm+), only mix them with fast, upper-water Tanganyikan Sardine Cichlids (Cyprichromis). NEVER, EVER put bottom feeders like Plecos or Corydoras in the tank; the Brichardi army will relentlessly attack their eyes until they are dead.

Reproduction: Unstoppable Cave Spawners (not mouthbrooders). Once the Alpha pair is established, they lay eggs deep inside the darkest rock crevice. You will never see the mating. Weeks later, you'll see a cloud of 50 tiny white fry hovering near the rock. Do not intervene. The survival rate is nearly 100% because the massive army of older siblings will violently slaughter anything that approaches the babies. It is one of the greatest sights in the aquarium hobby to watch 4 generations of a family working together.

Risks: 1. POPULATION BOMB (Tank Crash): They breed so prolifically and perfectly that in two years, your tank will contain 100 fish. If you do not regularly sell or trade the offspring, the tank will suddenly crash from extreme ammonia and lack of oxygen, killing them all overnight. 2. Sibling murder: Sometimes, a massive colony will mysteriously 'turn' on a single sibling and exile them to the top corner to die. 3. Massacre of any non-Tanganyikan fish thrown into their territory.
