The creek was relatively deep and fast flowing at this spot and compared to other times I have been here. I could see three distinct species of fish, but very difficult to photograph as I was a few metres up the embankment. This was the smallest of the fish species, about 3-4cm in length.
Interesting! This is Mountain galaxias. If you're certain there were 3 different species then I would say in your other photo is a trout species, probably rainbow but very difficult to tell. I was initially thinking it was also a galaxias. @MattBeitzel any thoughts?
Id suspect 3 age classes of Mountain galaxias. While trout have been known there >2 decades ago we have a survey site close by and have only had mountain galaxias at that for the last deccade
