I would suggest doing some research and finding that one fish that really sticks out to you (that will live comfortably in a 55 of course) and build the rest of the tank around it. I did the exact same thing you did. I rushed through the process because all I wanted was a fish tank setup. It took me many years to realize what I like and now I am deeper in the hobby than ever. I literally think about ways to make my fish more comfortable and make a better looking tank on a daily basis. It’s an addiction to me at this point, but it’s all because I found what I like and never looked back. It’s tough making a decision that you feel has to be the right one, due to the longevity of raising and keeping a fish but that’s what I love about fish keeping. You WILL make mistakes (we all have) but it’s a learning process and a really fun one if you can just figure out what it is that makes you tick. Don’t be afraid to step up. You will be glad you did.
Having said all that, I would suggest earth eaters and some other non-aggressive cichlids like acara, severum, ect. I have a tank with Geophagus Tapajos, clown loaches, roseline sharks, and an acara. I couldn’t be happier with the setup. My tank is a little bigger at 120 gallons but you get the idea.
Best of luck!
Thanks for the response, I really keep coming back to blue acara, but how can I tell them apart from a green terror?
