Macrostoma Male (M304)

Measuring 8 cm in length, this selected Macrostoma male delivers consistent lateral patterning and symmetrical fin development directly from controlled holding tanks. Sourced from a single breeding population rather than mixed wholesale batches, the specimen ensures that the scale contrast and morphology arrive exactly as photographed.

Breeders deploy this genotype in controlled crossing protocols to reduce unpredictable coloring across subsequent generations. The male also functions as a structured display centerpiece, maintaining clear visual definition when paired with pale substrates or muted foreground plantings.

• Documented Lineage: Ships with breeder-generated harvest parameters and trait consistency records, enabling transparent growth tracking and health baselining from arrival onward.
• Arrival Integrity: Exhibits active respiratory function paired with complete marginal fin tissue, confirming successful transport conditioning and osmotic stabilization.
• System Integration: Displays sustained locomotive behavior, supporting straightforward community placement once introduced alongside compatible freshwater inhabitants after following standard parameter ramp-up schedules.

Transit packaging prioritizes dissolved oxygen retention and thermal buffering to preserve structural stability throughout shipping windows. Gradually adjust osmotic pressure to align with your primary system’s pH and temperature ranges before final release into main tank filtration cycles.
