Exasperatus – Psuedotropheus joanjohnsonae

Exasperatus Cichlid – Pseudotropheus joanjohnsonae 

The Exasperatus Cichlid (Pseudotropheus joanjohnsonae) is a striking and relatively rare species of cichlid native to Lake Malawi, Africa. Known for its vibrant coloration and territorial nature, it is a beautiful addition to an aquarium for hobbyists experienced with African cichlids. This species is often appreciated for its unique appearance, marked by a vibrant blue body, and its engaging, albeit somewhat aggressive, behavior. Though it may be a bit challenging for beginners due to its territorial tendencies, it thrives in well-established tanks that mimic its natural environment.

• Common Name: Exasperatus Cichlid
• Scientific Name: Pseudotropheus joanjohnsonae
• Size: 4.5–5 inches (11–13 cm)
• Lifespan: 6–8 years with proper care

The Exasperatus Cichlid is a medium-sized, colorful species that grows to around 5 inches in length. While it may not be as widely available as other African cichlids, it is highly valued by enthusiasts for its striking color patterns and dynamic personality.

• Habitat: Native to Lake Malawi, the Exasperatus Cichlid inhabits rocky environments at varying depths, typically found in clear waters with moderate to strong water flow. It thrives in areas where it can graze on algae and small invertebrates, much like other members of the Pseudotropheus genus.
• Behavior: Pseudotropheus joanjohnsonae is known for its territorial nature, especially males. During breeding seasons, males may become more aggressive, defending their territory and displaying their brightest colors to attract females. Despite its aggression, this cichlid is generally peaceful towards females and other species that do not pose a threat to its space. They can, however, show aggression toward other males of their species and other similar-sized cichlids, so providing adequate space and hiding spots is essential.
• Tank Size: A minimum of 55 gallons (210 liters) is recommended for a small group of Exasperatus Cichlids. A larger tank is beneficial to allow for proper territory spacing and to minimize aggression between males.
• Substrate: Fine to medium gravel is ideal for this species, as it replicates the rocky, sandy lakebed where they naturally dwell. You may also incorporate a mix of sand and rocks to create a more natural environment.
• Diet: The Exasperatus Cichlid is primarily herbivorous, feeding on algae and plant matter in its natural habitat. In captivity, you should provide a diet rich in vegetable matter, such as spirulina-based flakes, algae wafers, and blanched vegetables like spinach and zucchini. Supplement their diet with high-quality protein sources, including live or frozen foods such as brine shrimp or daphnia, to promote healthy growth.
• Feeding Schedule: Feed 1–2 times daily, offering only as much food as they can consume in a few minutes. Overfeeding should be avoided, as it can lead to water quality issues.
• Decor: Provide plenty of rocks and caves to mimic their natural habitat. Exasperatus Cichlids are rock-dwelling fish, and these structures allow them to claim territories and hide when they feel threatened. It is also recommended to provide some open swimming areas, as they are active swimmers.
• Water Conditions:
  • Temperature: 76–82°F (24–28°C)
  • pH: 7.8–8.6 (alkaline)
  • Hardness: 10–20 dGH (moderately hard to hard)
• Lighting: Moderate lighting that simulates the bright, clear waters of Lake Malawi is ideal. Ensure a consistent day-night cycle to keep the fish’s internal rhythms intact.
