Special requirements
Complex Burrow Reproduction
In nature, they excavate complex burrows with multiple false entrances. In aquaria, a large upturned flowerpot is a necessary substitute for breeding.
Intraspecific Aggression Management
Prone to unpredictable, lethal aggression toward their own kind. Large tanks and group sizes are required to diffuse this behavior.
Pristine Water Stability
Susceptible to HLLE (Hole-in-the-head) if water quality slips. Requires high-efficiency filtration and massive weekly water changes (50-70%).
Dietary Carotene
Requires a varied diet including vegetable matter (Spirulina/Spinach) and high-quality meaty foods to maintain its signature trailing threadfin color.
