Special requirements
Sand Substrate
Essential for benthophagous 'earth-eating' behavior. Coarse materials like gravel can damage sensitive gill filaments or cause internal blockages if ingested.
Pristine Water Quality
Highly susceptible to deteriorating water quality and HLLE (Head and Lateral Line Erosion). Requires massive weekly water changes (50-70%) and over-filtration.
Social Grouping
Must be kept in a group of 5-8 individuals to establish a stable dominance hierarchy and prevent excessive bullying of weaker specimens.
Fine-Grade Diet
Even as adults, they cannot properly ingest large food items. Feed multiple small portions of fine-grade sinking foods daily to allow for natural browsing.
