Field Notes
Description:
Small endemic solidly built fish. Non breeding males and females are pale brown with darker brown blotches. Narrow pale vertical stripe at the base of the pectoral fin and usually three fine brown stripes (look a little like whiskers) running horizontal below the eye on the cheek. First dorsal fin has 7 spines. Head slightly more elongated than other Bully species. Fish found in streams with access to the sea have several well defined head pores but in lake fish pores are not always present or obvious. Can grow up to 120mm but usually 100mm and lake fish tend to be smaller.
Habitat:
Found in streams with access to the sea, however fresh water colonies will readily form in inland lakes given the opportunity. These fish were caught and released in Lake Taupo in Central North Island of New Zealand.
Notes:
Common Bully's can be frustratingly similar to other species but the combination of ID markers and the location of these fish make identification certain.
