Bare in mind most pics youll see are of adult males....very different to a juvenile form.

Although i could be wrong, its just what it reminds me of. There is way to many ciichid species out there its quite confusing, Anyway i hope i got it, Best of luck Angel
EDIT: Highly doubt its a convict guys..it only has five stripes and its too 'slender'... Also think both pics are the same species, just the second one is a little older (hence the blue tinge)
