Interesting post, Richard. We DO need to see if we can make it a "sticky". BTW, didn't you and Mark dip fish - especially CBB - for flukes?

Back to my hippo - when I say he/she gets regular outbreaks, these ARE minor - and the fish eats just fine. Only rarely do any of my others have ANY spots - if they do, it's just 1 or 2. The hippo will have 10 or so on each side. Interestingly from Steven's article, the hippo sleeps in the SAME place every night...
