i would, wait til you get the 55G,
then go for some nicer cichlid, rams are ponsey face it...
there are plenty of smalelr sized non dwarf cichldis that are easy to keep and breed in a 55g.
firstly are you aim ing to keep and breed a singualr type of fish? or have jsut a mixed tank of cichlids.
because only certain fish can go together.
if you was aiming to breed a fish, id go for
convict,
firemouth,
jade eye cichlid,
salvini's,
a singular pair would love a 55g.
but if you wished to have a variety of fish, you decide on wether u want aggressive or gentler fish,
convicts being fairly small and aggressive, whilst the severum can get quiet large, but still is a peacefull fish ( alot of the time ) you could get blood parrots etc. the list goes on!, search the cichlid index on this forum and gather information on the various diferent types of cichlids
hope that lengthy reply helped
