Hi fish forums. My 55 gallon holds a firemouth x1, Blue acara x1 convict x1 and a rainbow shark x1. All of them are still small being the biggest only 4 inches. I was just wondering if im able to put any more fish in there. Maybe a nice looking a cichlid or a group of dithers. If you know any good cichlids or dithers that could go wit my setup pls tell me and help me out. Thank you if responded.
