He's eating nori!
Wonderful! You will find that these fish eat mostly veggies - ours will eat mysis also (but then he's a little piggie). I would also add Spirulina to his diet. You can get the frozen cubes which are really easy to feed, and your Tangs will also benefit. As far as his shyness - Hmmm...what type of Rabbitfish do you have? We have a Virgate Rabbitfish. I remember when we introduced him to the tank, he wasn't very aggressive, but he was well versed on how to defend himself if the Yellow Tang bothered him...YTs seem to be very territorial. Now, he bosses the YT. I would give it some time. If he is fed well, he will grow fast (ours sure did!), and since he has venomous spines, the other fish will quickly learn to leave him alone. One thing I will definitely recommend though - keep nori in the tank at all times! If your RF doesn't have something to nosh on, he may start eating your corals. I caught ours eating a nice colony of green zoas about three or four weeks ago, and now I make sure there is always some nori in the tank. They like to nibble on something *all* day long.

I've also noticed something else that I thought was rather funny - our RF never really slept in the rockwork when he was in the 75G. I thought he would once we got the 210G, as there are LOTS of caves for all the fish to share. Know where I caught him sleeping? Vertically - right next to the overflows. :roll

I wouldn't worry about taking out the rocks and rearranging - at this point, I think it would just add undue stress to your RF AND all the others.

Good luck with him, and keep us posted on his progress ;)
