Get a rapheal if you want, but you probably wont see him. I have one, and it is VERY elusive. That's what they do. He does scavenge the bottom though, and it is a nice treat when I do see him.
hoplo, and porthole catfish. Much better for the community ype setup than pictus, are almost to peaceful for their own good, and get to a good size, 4 ish inches.
I was int he same situation you were in, and instead of cories, I opted for hoplos. much more interesting to look at, ame basic personality.
