Thanks folks, appreciate it ! :-) Will not reply to each post, but don't
take that as rude please, just don't want to hog the NG.

Forgot to say that on this pic
http://www.wide-o.net/summerpond2003/PICT0003.html (top centre) you can see
how the pectoral fin of a wounded koi I bought is growing back like nothing
happened. Only thing missing is the color, but I'm told that might come
back too.

Theo, Those were some of the best pictures of a pond that I have ever
seen.
Your pond is beautiful. Doug
