| Habitat |
Most common on soft, silty substrate, but can also be found on any solid objects that protrude from the bottom. They have hemoglobin which allows them to survive in habitats with very low DO concentrations, such as small, warm ponds. |
| Feeding Information |
Mostly collector-gatherers, some scrapers. They consume living algae, fine detritus, and living aquatic plants. |
| Water Quality Tolerance |
Facultative to somewhat tolerant. |
