All very nice choices!!! The first argentea pic is amazing gotta love the heckelli, wow!!! Green terrors, istlanums, and beani look very nice too. Keep them coming. Looks like I will have to put a poll together
I think Haitiensis also.....its not just the trailers, even their tail fin is large and graceful. This one isn't mine but this is the dad of my old one:
Imo, the Thorichthys genus has the best finnage - specifically, the maculippinis/ellioti. It's a beautiful red at the tips, and how it trails make it look just magnificent. Sadly they don't grow large, but still.
heres my contribution to some awesome finnage. my hoga has always has some awesome high, full and long extending fins since ive had him. here he is @ 9" cant wait till he reaches 12"+
