Small, non-descript silver fish. Females up to c.6 cm, males up to 3.5 cm.
To help protect our environment:
Shallow margins of still or slow-moving waterbodies, lakes, wetlands, ponds, streams.
Eats zooplankton, eggs and larvae of fish, aquatic and terrestrial macro-invertebrates. Can contribute to poor water clarity, alter nutrient cycling and exacerbate algal blooms.
Check equipment and vessels for freshwater pests, clean everything that has been in contact with the water and dry everything thoroughly.
