Emperor Or Rainbow Tetra...

[bogwood]

Originally, I was after a small group of Glowlight Tetra, but I'm now thinking of getting either 6 Blue/Purple Emperor Tetra (Nematobrycon Palmeri) or 6 Rainbow Tetra (Inpaichthy Kerryi) for my 20UK gallon community tank. Of the two, is one easier to keep/more hardy? They look very similar - are they a variation or seperate species? Also, if anyone knows where in the Berkshire area I can get them - as my lfs doesn't stock.

Both are of the genus Nematobrycon.. being N lacortei and N palmeri, so they are genetically very similar, requiring identical conditions, and both being reasonably hardy. No idea if there are any aquairum stores in berkshire though someone else might, but as a last resort you could mail order them?

I've had a look at Tri-mar's website.... are there any other online fish sellers in the UK?
