I needed to move an Ocellaris today, so I DID reach in and scoop him up with both hands. No fuss, no muss; I've done this many times. They like to swim into your hand, just bring the other hand on and keep covered during the transfer.I'm constantly amazed how trusting tank-rased ocellaris clowns are. I can practically reach in and grab them with my hand (not that I would...) The clear container trick works great: Food in the container, clown follows. One of mine has gill parasites. So catching him for a FW dip was a no-brainer.
Any good links for clown gill parasite info?
