lol...my cbs does all of the above. Especially when I spot feed my brittle stars and linkia, he just HAS to come by to see what everyone is eating. Of course, I think I have spolied him(her?-sorry!) by spot feeding him as well during this whole thing. I just feel bad....he watches everyone else get fed, so I just give him a bit too. Even when I vacuum the tank, he runs over and I think he actually watches, because he doesnt even attempt to grab any detrius that may come up and escape the siphon...its actually like he is genuinely curious. Love this little guy! Been with me for almost 2 years now and what a personality!
