Thanks for the invitation Stella! On the chance I'm up your way I will definitely take you up on it!
Well I don't yet know how many species I have, as I've yet to identify my recently acquired whitebait (20 of whom I caught about 6 weeks ago). I assume they are mostly inanga (possibly a few dwarf inanga??), but I'd love it if one or two were koaro (or maybe even a giant kokopu if I should be so lucky!). I will let go any inanga out of this lot.
So here's what I have:
4 little bullies which I imagine must all be common bullies (from two different small river tributaries in Upper Hutt and Wairarapa).
One sizable male redfin bully who you kindly identified! (from a large stream in Kaitoki, Upper Hutt). I've had him about 3 months in a darkish tank and his original stream/river was semi shaded.
One juvenile banded kokopu by the looks (as per photo) from a creek in Eastbourne.
Two fully grown inanga from an inner city stream in Lower Hutt (the one behind the library).
20 whitebait of unknown species from the Ruamahanga river at Lake Ferry, Wairarapa.
One little (15cm long) timid eel of unknown species from the Tauherenikau river in Wairarapa (of an unusually light brownish colour, almost as if it were an albino??)
So if I'm lucky with the whitebait I might have 6 different native fish species... A pair of mudfish to breed would be a dream come true! As would a smelt or two, a torrentfish, a short-jawed kokopu, bluegill bully or a lamprey (no harm in dreaming is there?)...
I have a few WCMM but I think they will have to go to new homes when/if I procure some more natives.
I would like to get into breeding at some stage but I think I'll need yet another tank for this as I need the two tanks I have just to accomodate all the above (along with a few crays, two mussels, snails, worms etc)...
Below is two photos of another one of my little (common?) bullies.
What are your eight species?
Oh, I just saw a picture of an upland bully with blue around the gill openings. Do you know if common bullies sometimes also have this blueish tint? If not, then I may have had a big upland bully once which I thought was another common bully and so put it back in the river.
