Hello. I began my fish tank ownership with cichlids about 15 years ago with an experienced cichlid owner and about 12 years had to let the tank and all the fish go. Now my boyfriend and I are ready to start a tank again and I want to do cichlids because of their great personalities and beauty. We have a 75 gallon tempered glass aquarium and nothing else so far. I was looking at some of the 3D backgrounds and I think I'm interested in doing that. Any advice, comments, or suggestions? Thank you so much!
