Myleus rubripinnis (Red Hook Silver Dollar) Variations?

[pwmin]

I got two redhooks (lost one) and they seem to have really long anal fins. I see some w/ shorter and some longer (none that these, however). Have ya'll noticed this, too? Here are some pix:

Yes Over the last several years I had noticed that the fins haave gotten short on some of the "red hooks". I belive that some where along the line they have been cross bread with another type of siver dollar. Those causeing the short fins. If you are lloking for the true Red Hook, you know what they say. Longer is Better.

makes sense...maybe w/ the other dollars you can see in the pix which some people call redhooks but arent
