I have 6 Serpae and 6 neons in my tank. 5 of my serpae's are fairly large and round and light amber in colour, but 1 of them is about the same size as my neon's and has very dark markings around its spine. It also doesn't swim with the others but is often on its own, it is still eating, but I am worried that something is up with it? Any advice is much appricated.

It is probably another species.
These fish are collected in the wild and several diferent species that look similar can be collected at the same place.
These fish are known to the serious hobbyist as contaminates.
A lot of fish that do not normally get shipped in, can sometimes be found that way.

As long as the fish acts like a normal fish, I would not worry.

By the way, Welcome to Fishlore!!!!

Thank you for the advice and for the welcome.

My fish has now died, I think it was just a poorly fish, can't believe how upset I feel.

I'm so sorry you lost your fish.

by the discription it sounds like the other fish is a phantom tetra maybe you should look thagt up and if it looks like that other fish then maybe try to get a school of them. :-)
