yup... not a jack Dempsey, that is an aequidens rivulatus. I would return it to the store, you probably overpaid, small GT's should be very cheap and EBJD usually pricier. Also the GT will grow just a bit too large for a 55.
Also, I think you may have issues with just the two electric blue cichlids in the tank, most likely whichever is dominant will bully the other with no other cichlids to distract them, and especially since they would look similar.If I were you and I really wanted the EBJD, I would sell the acara off and let the EBJD have the tank with the SD's etc
