I am looking into red parrot cichlids, my wife really likes them so I am trying to see if I can get a pair to work for us. I am not finding allot of info on them, is there a more common name for them that I can look up them by? I know they get pretty big but I am not sure how big. I am wondering if I can fit a pair of them in a 37 gallon tank, if I remember correctly the dimensions of the tank are 30" wide 24" tall and 12" deep. I think the tank is a little small but if it was just the 2 cichlids and no other fish would that be okay?
