I am meaning lake hayes, it is a smaller warmer lake than lake Wakatipu. They are a brown colour and swim in huge schools of maybe 50+ all in the sam direction, they are about 6cm long. I think they maybe baby Koaro or bullies. How big tank do you need to keep them?
I also noticed a small brown but more camoflauged than the other fish they was more flat but about the same size that swam in a similar way to a pleco. I was swimming on its own and would swim then stop and sit, then swim again.
There is an aquatic plant that grows in patches. It is grass like, Similar to hair grass but shorter and further apart. Is this a native maybe lilaeopsis novae zealandiae?
What to you need specifcally for a native tank. ie. size, equipment.
There is book at the libary about native fish found in the otago region, I think I will get this out. I know we can get freshwater crayfish and know were to find them. Now that I think of it you can get galaxids on the Routeburn too.
