Malawi Mbuna Cichlid Thumbi West OB (Size 1.5") | Single

The Malawi Mbuna Cichlid Thumbi West OB (Size 2" to 2.5") is a captivating and lively species originating from Lake Malawi, specifically from the rocky shores of Thumbi West Island. Known for its unique Orange Blotch (OB) pattern, this cichlid is admired for its unpredictable and striking coloration, which distinguishes it from many other cichlids.

Appearance: At 2" to 2.5" in size, the Thumbi West OB is still juvenile, but it already exhibits its iconic OB pattern, where irregular splashes of orange, yellow, and red are layered over a base of grey, blue, or white. The intensity and distribution of these colors vary, making each individual fish unique. Some may have brighter orange splotches, while others lean towards more subtle blends of yellow and blue. Their fins can also display hints of blue, black, or orange, contributing to their vibrant and eye-catching appearance.

Temperament and Behavior: As a member of the Mbuna group, the Thumbi West OB is known for being territorial and aggressive, especially in smaller tanks. They are highly active fish and are constantly exploring their environment. In the wild, they live among rocks and crevices, which they use for hiding and defending their territory. In captivity, they thrive in rock-heavy aquascapes that mimic their natural habitat. These fish are best suited for tanks with other Mbuna species or similarly aggressive cichlids. While they can be aggressive, this behavior can be mitigated by keeping them in groups and providing plenty of hiding spots. Overcrowding in tanks is often used to spread out aggression, as it dilutes territorial disputes among the fish.

Tank Setup: To keep a Thumbi West OB healthy and happy, it is essential to provide them with a tank that mimics their natural rocky habitat. A tank size of at least 250 litres is recommended for these active fish, as it gives them enough space to establish territories. Rock formations, caves, and hiding places are crucial, as they provide shelter and reduce aggression.

They prefer a pH level of 7.8 to 8.6, reflecting the alkaline waters of Lake Malawi, and the water temperature should be maintained between 75°F and 82°F (24°C to 28°C). Clean water with strong filtration is important, as these cichlids are sensitive to water quality.

Diet: In the wild, Mbunas are largely herbivorous, scraping algae off rocks and consuming small invertebrates. In an aquarium setting, the Thumbi West OB does best on a diet of high-quality spirulina-based flakes, pellets, and vegetables such as spinach or zucchini. They should also be given occasional protein-based foods, like brine shrimp or daphnia, but avoid excessive protein, as it can lead to bloating and other digestive issues.

Compatibility: The Thumbi West OB can coexist with other Mbuna cichlids or similarly aggressive fish from Lake Malawi. It is not advisable to keep them with peaceful or slow-moving species, as the Thumbi West OB may bully or harass them. To help control aggression, a ratio of one male to several females is recommended if breeding is a consideration, as males are typically more aggressive.
