Spangled Perch is a remarkably hardy species that may be capable of surviving droughts by aestivating in wet mud or under moist litter on the bottom of ephemeral waterholes. However, conclusive evidence is lacking. Spawning occurs on summer nights (November onwards) when water temperatures reach 20 - 26C. Fish move upstream in rivers or to the shallows in lakes and ponds to spawn on soft substrates. The eggs hatch in two days and larval development is complete in about 24 days.

They are tough alright, I found the above fish crossing a road in just a few mm of water.
Not even enough to cover him when on his side.
I scooped him up and helped him on his way.....hope it was the side he was heading to.
