I
am a nesting male. When it is time to breed I change
from my usual spotted colour to black with an orange
tip on my fin. I will guard my young until they
hatch and I attack if you come near.
I usually live in slow streams, but you will find me
almost anywhere in a swamp, lake or river. When I am
not nesting I swim around with others. There are
lots of us in Waitakere because we can eat lots of
different things. We always hunt on the bottom of
the stream where we look for insects or small
crab-like animals.
