Three types of fish can also be found in the wetlands: Common Galaxia, Short-finned Eels and Mosquitofish (an exotic pest species).
This species was last seen in 1948 and is believed to have gone extinct in the early 1950s, likely as a result of habitat alteration and competition with and predation by introduced crayfish Procambarus clarkii, mosquitofish (Gambusia affinis), black mollies (Poecilia sphenops), and bullfrogs (Rana catesbiana).
