Hi Mustang man ,
Maybe while the fish are still on the small side [ and living ], you can find out the max sizes they grow to , some of those[ single specimens ] full grown are to big for your 55 g by themselves . You could decide on what you may want to keep. And trade off the rest .You might be able to keep the JD , firemouth and the con , but the others will get way to big .
You might want to consider dwarf cichlids or other dwarf sized fish .
And welcome to the forums
