I like the way he looks in both outfits. As part of the diet for mine I feed them Hikari Bio Gold pellets....it's for carnivorous fish...has some garlic to make it irresistible. I got my pair when they were around 6" and I think the were only feed feeders but that's a guess. They didn't seem to interested in anything after the initial splash into the water. The started tearing up krill in no time along with bloodworms and it took a couple of days but they love those pellets now as well. Might want to give those's a try if you haven't already.
