Macrostoma Male (M353)

This 8 cm Macrostoma male (M353) delivers a fully documented, breed-selected phenotype that matches the product imagery exactly, removing speculation from selective acquisition. Each unit represents a measured drop from controlled holding rather than pooled wholesale inventory.

The specimen exhibits standardized scale contrast, symmetrically developed fin rays, and sustained locomotion during handling—biological indicators confirming successful transport conditioning. Visual uniformity eliminates the retail discrepancy between photographic representatives and shipped inventory. To maintain accountability, every individual ships with breeder-generated documentation outlining harvest parameters and observed trait consistency, giving keepers transparent lineage tracking from arrival onward.

Dedicated Application Guidelines

• Phenotype Locking: Deploy verified males in controlled crossing protocols to reduce unpredictable coloring in subsequent breeding generations.
• Display Centerpieces: High-contrast lateral patterning maintains visual clarity against pale substrates and muted foreground plantings.
• System Integration: Baseline activity levels indicate straightforward acclimation alongside compatible freshwater communities when following standard parameter ramp-up schedules.

Transition requires gradual osmotic adjustment to align with your primary system’s pH and temperature ranges before final release. The male arrives with intact marginal fin tissue and active respiratory function, supporting rapid establishment in properly filtered housing. Packaging prioritizes dissolved oxygen retention and thermal buffering throughout transit windows to preserve structural integrity and minimize post-delivery stress responses.
