We made 2 dives of 90 minutes each looking at a stash of Sailfin Blennies. In 15 feet of waters in a patch of rubbles there must have been more than 40 of them. The male were very friendly and dancing for us (FYI - Only the male dance. Males are darker). I used my 100 mm canon lense to shoot the pictures. You must use a 1/160th and up to be able to clearly capture these little buggers. We used the AI focus also (got a cramp from holding the trigger). We have not begin to work on our Bonaire pictures from may yet but wanted to put a picture of the Sailfin for Todd & Lynn Fulks (We met Lynn at the Carib - She was completing her Divemaster course). Todd - Hope you have found the blennies yourself and have taken some good shots. If not hope this will inspire to find this very special stash :*)
