Platys

[Proterra]

I'm not very good with recognising fish but is there a variety of Platy that has a top fin that is longer from its head to tail than normal? Its not a high fin just a longer one.

Thanks.

The 2 main types of fancy platys with extended fins are high fin and sailfin platys and both types can breed with standard platys, your platy is most likely either a high fin or a sailfin platy

Something like this?

might be a sail fin I think then rather than a high fin. Its pure white. Was just curious as its my favourite fish in my tank - keep trying to get a picture of it but its not being very co-operative.
