Hi,

New to the forum but have found it very useful as I set up my new koi pond!

Quick question regarding butterfly Koi; i'm looking to add a few of these to my pond but one thing I noticed is that many of the fish tend to have transparent fins - do these tend to colour up as they get older at all? I was trying to find a platinum white fish with long white fins but it seems to be nearly impossible! I saw a few orange fish with white fins but the fins themselves weren't as long and flowing as the transparent fins...

Many Thanks In Advance!
