Sites with mudfish generally have overhanging vegetation and tree roots, and demonstrate low to moderate human impact. Once widespread in swamps and wetlands, mudfish are now found in only a few sites and mostly on private land.
Mudfish can do something that most other fish can’t: they can survive without water for almost two months! All they need is vegetative cover to keep themselves moist. Then, when summer is over and water returns to the wetland, they can eat, swim and breed. This type of adaptive behaviour means that mudfish can live in places other fish can’t.
