Ah, that was dumb of me, Lacustris is NG isn't it? I was thinking of one of the australian species from Kangaroo Creek - so you reckon it's duboulayi? I can't get an accurate ID with blurred photos of juveniles, but people who've bought them say that the adults when settled into their tanks are magnificent. I'm pretty sure Melanotaenia 'Wallaby Ck' is trifasciata, and the Murray River Rainbowfish is almost certainly fluviatilis, I don't have an accurate locality on those. Murray River is part of the Murray Darling system, the biggest river system in Australia, so without an accurate collection location the name of the river doesn't mean much.
The problem is that they are all grown on too fast and fed rubbish when they are young, so they never come into their proper colouration. I collect my own whenever I can, but my parents have this funny thing about not liking to stop next to creeks while trying to get somewhere so I can climb down the bank, get filthy, and reappear with yet more fish bags. Wonder why that might be.
It always surprises me that there are relatively few rainbowfish breeders in Australia, they are stunning fish but there are only a handful of people who are really dedicated to maintaining the best coloured Australian lines with separate tanks for each species/locality. They hybridise readily, and there are actually natural hybrids near where I live. I think they're one of the main reasons why there are still arguments about taxonomy.
