Anyone can help

If you want something different in that size tank, look at going to saltwater. There are literally THOUSANDS of fish options you can keep in a 45 gallon. I'd do some rock and dozens of small fish that live on the rock or close to it. You could also add various inverts as well. The activity level would be amazing to watch.
