I see lots of beginers buy dempsies & convicts(along with oscars & managuense) to put in unsuspecting community tanks. I like & breed both before. I have to get back into the hobby but rest assure there is nothing like a good 6 in male nigrofasciatus (convict), a 8-10 male octofasciatus(dempsey) is regal also. the LFS in my area just keep a big group in bigger tanks a have less staple cichlids in the smaller tanks.
