Different kinds of rummynose tetras?

[Savant]

I understand from some previous reading that I had done some years ago that there are three different kinds of Rummynose tetras and that the difference is in the intensity and size of Red area in the nose of tetras.

Can anyone care to share if the above is true and whether they are different species or merely variants?

There are three different species. However, there also seems to be an aquarium strain known as golden rummynose (which I *think* is the albino strain).

Golden rummynose don't have the red eyes so I think it can't be considered albino? The tail marking is less distinct though.

The problem is I am not qualified enough to say if they are or not, hence the emphasis on *think*.

One thing that I found out though is that, many see albinos as persons with white hair, white skin and red eyes, but that is actually a myth (not helped by the stereotypes in popular culture like films, TV). People with albinism can have normal eye colour (e.g. light blue, hazel, brown and so on). Besides that, there are many forms of albinism, where some may not be easily distinguished by appearance, and genetic testing is generally required to be certain.

That said, the above seems to be in context of human beings, not necessarily on animals.

Perhaps, leucism may be the better term as it slipped my mind at the time. As I understand it, leucism is similar to albinism except that the eye colour in the affected animals are always normal.

Some books put the common rummy nose(the ones with black spots on the tail) we find in the LFS as false rummy nose but the LFS mix with the non black spotted tails and still call them rummy nose
