Procambarus fallax
A freshwater crayfish that moves through the lake and shoreline as a grazer, scavenger, burrower, and small-scale habitat shaper. It feeds on soft growth, detritus, small animal material, and plant tissue, including older Tapegrass leaves.
Slough Crayfish are established in the Freshwater Lake and Lakeshore, with repeated breeding and several generations observed. The exact number is still approximate, but crayfish remain active and visible in the system.
Slough Crayfish are flexible omnivores. They graze, scavenge, disturb sediment, and move energy from plants, soft surface growth, and decaying material into the animal food web.
This section will expand as more information is documented for this species.
Has reproduced successfully with now 5 generations since January 2026
Their digging and feeding can reshape small areas of the lake floor and plant edges. Recent feeding on older Tapegrass leaves suggests they may help move aging plant material back into the food web, while the strength of that pattern is still being watched.
Follow this species across the habitats where it currently appears in the miniBIOTA biosphere.
Slough Crayfish remain one of the larger consumers in the rebuilt post-removal lake food web.

Water tests in the lake biome showed ammonia, nitrite, nitrate, phosphate, and pH all in good condition, even as algae and clam surfacing continued. The update pointed toward nutrient competition, Ludwigia root effects, crayfish activity, and crickets spreading across biomes rather than a simple water-chemistry failure.

Ludwigia in the lakeshore ecosystem was establishing better than expected despite crayfish pressure. As the plants produced dead leaves, they were expected to feed and shelter amphipods and isopods, while grasshoppers on the land side continued to graze but may have been escaping through vented atmosphere openings.

miniBIOTA 2 became muddy after new plants were added, but the mess was expected while the plants established and crayfish rearranged the habitat. Grasshoppers were also introduced on the land side to graze grass and return nutrients to the soil, setting up a multi-week test of nutrient turnover.
Corrected from Marine Shore after user clarified miniBIOTA 2 was the older freshwater-side system.

With Hurricane Milton threatening Orlando, miniBIOTA 2 faced a possible power-loss event. The system appeared less vulnerable than the earlier crash because the water held less algae and therefore less immediate oxygen-collapse risk, but the lake still contained fish, crayfish, snails, and other diversity that could be affected by a prolonged outage.
