Karen,
I'm interested in the neon dottyback, but since you mentioned that he may pick on smaller fish, I have a target mandarin that's about 1.5 inches. He's the smallest fish in my 55G and is my wife's favorite, so I wonder if they'll get along. What do you think?
The sea apple also seems interesting but I read that they're difficult to keep, espcially since I'm in the process of moving everything to a 75G. So maybe I shouldn't consider it at this time. What's your experience on keep it so far, how easy or hard is it?
Thanks,
John
