Are They Blood Fin Tetra?

They are a very pretty fish!

They don't look quite right for flame tetras, aka von rio tetras. And they don't look quite right for bloodfins either
I've seen albino cherry barbs recently and although the colour is right the body shape of your fish isn't quite right.

They could well be an albino form of a fish we see quite often in shops. There are more and more of these colour morphs appearing.


Did you ask the shop what the wholesaler's invoice gave for their latin name? That's sometimes a help, though the wholesaler often uses just the common name.
