I haven't tried to figure them out, but I just figured the Magics are all correct to start with. That would put the
greenfin on the Spotanus ... Maybe give the Beta the twin fin?

Putting The pink fins on the Arrowfish make him look more like an arrow. But it makes sense the Quicksilver would be finless cause ya can't see the rest of him anyway!

I wish I had room to keep a tank of my favorites just for 'looken at'. But each time I set one up I get some bright idea of something else I'd like to try, and sell them all all.

It would be nice to have a 'keeper' tank of those perfect 21! ... I don't think I'm any help in figuring them out though!
