Not quite, there is one I'd like to get called(oldname) Cynolebius nigripinnis, last seen at a fish show held by the NZKA.
It was stated that young ones were held by the presenter, but I've seen nothing of them.
I fear the worst but hope I'm wrong.
They are a killie that can take LOW temps, having survived at one of our NZKA member's place, outside, at Wellington, through winter, in a water butt.
I'd love to see them resurface in the near future.
