Theo,
The picture looks like it's just a bite out of the fin, if the main frontal
ray/bone is still there, undamaged, the whole fin should recover.... what I
can tell from the picture, if I'm seeing what I'm seeing..... I bet within
1 or 2 years all is fine. So you got a good deal. ~ jan
PS If one ever has a pretty fish with a whole fin missing don't point it
out. I went to a meeting and the prettiest fish we all ooh and aah over had
a pectoral fin totally gone, none of us even noticed till the owner pointed
it out.
