Other bullies
Upland bully
The upland bully and cran's bully are non-migratory bullies. They are difficult to tell apart in the field and both lack the head pores that other bullies have. They can grow to about 8 cm long and can be found in a variety of habitats.
Just to add to the confusion there are some marine fish that like to venture into freshwater from time to time. These include the black flounder which can be found a long way inland, the yelloweye and grey mullet which cannot live permanently in freshwater but penetrate large northern rivers, the stargazer which prefers salty water to fresh, the cockabully which is found in estuaries, the yellowbelly flounder which can be confused with the black flounder and the kahawai which despite being a marine fish can move several kilometres upstream.
