Mike, how long have you had him?
Mine is a goofball and a pig. My scopas is a little turd and will hound the foxface for his food. The foxface will grab a big hunk of nori and take off with it and the scopas will go after him and try to pull it out of his mouth, even though there is other nori available. If he gets away with it, he goes swimming off like "Yay, I won!", and the foxface, if a fish could roll his eyes, slowly goes over to him and yanks it back. After my foxface eats, he then will go to the top of the tank and gulp air and let it bubble out of his gills as he sinks back down. Not sure why he does that, but I've seen from some postings on RC that he's not the only one.
