Real F1
Appearance: This variant is part of the group found south of the Burundi-Tanzania border down to the Malagarasi River. In rocky environments without sediment, they display clearly visible vertical stripes, a thin yellow spot on the top of the body, and a light yellow spot on the belly. In sediment-rich habitats, their color is more uniform (dark green to blue-brown) with less visible stripes.
Size: Adults reach approximately 14 cm (males) and 12 cm (females).
Habitat (Biotop): They live in rocky environments but are more tolerant of sediment-rich areas than many other Tropheus species, allowing them to inhabit shallower waters.
Tank Requirements: A minimum of 400 liters (length of at least 150 cm) is recommended.
Setup: Fine sand substrate with many rocks to provide hiding places and visual barriers is essential.
Water Quality: They are sensitive to ammonia, nitrites, and nitrates. High oxygen levels and regular 30–50% weekly water changes are necessary. pH should be 7.5–9.5, and temperature should be 25–27°C.
Aggression: This is considered one of the most aggressive Tropheus species. High intra-specific aggression means they should be kept in large groups of 15–25 individuals (ideally 3–4 females per male) to distribute the aggression.
Diet: Strictly herbivorous. In an aquarium, they should be fed high-quality spirulina flakes and must avoid high-protein foods to prevent "bloat."
Breeding: They are maternal mouthbrooders. Females carry 6 to 16 large eggs for 24–26 days. Unlike most other mouthbrooders, the females continue to feed while carrying the fry.
