I found most people have asked me for HMs, because they have wider, fuller fins that make them more "majestic" looking when they swim in the water.
Personally, I am going for HMPK cross to a regular HM and I would like to breed short to medium length fins from the spawn. I love my dragonscale HM... But here is a before and after picture.
I find, though it LOOKS nice, it really isn't what I like. The fins are too fragile, too thin, too LONG. And yet it is what people want. I want to be able to keep the neat looking 180, but shorten it so the fish can still swim without a problem.
NEED before WANT.
Edit: BTW there are no sharp plants for this fella. Not even common hiding spots, to avoid the sharp edges. He has a bell, and some plants.
