Macrostoma Male (M292)

Every 8 cm Macrostoma male ships as an individually selected specimen rather than a pooled batch, ensuring scale contrast and fin symmetry align precisely with our catalog photographs. We pull directly from controlled holding environments and perform pre-shipment vitality checks. You will receive a fish with intact marginal fin tissue, active respiratory rates, and consistent forward locomotion right upon opening.

Oxygen-retentive, thermally buffered packaging protects the specimen across extended transit periods, minimizing osmotic shock and preserving structural integrity. Each unit accompanies complete breeder origin documentation to record harvest parameters and physical trait consistency, establishing transparent health monitoring from your first day with the fish.

The pronounced lateral patterning functions effectively as a display centerpiece against pale substrates and muted foreground aquascaping. For captive breeding cycles, deploying this verified male reduces random mutational coloring and stabilizes predictable phenotypes across subsequent clutches. Maintain the animal in adequately filtered freshwater systems with stable nitrogen cycling. Compatible with non-aggressive tank partners sharing similar water chemistry requirements. Standard acclimation protocols apply: gradually match tank temperature and pH before final release to prevent stress-induced flagging. Monitor ammonia and nitrite levels closely during the initial two-week settling phase, then transition to routine maintenance feeding schedules.
