I'm about to move to a new house and I want to get out of salt water and go back to fresh. I am looking at getting a tank between 120-210. It will be bare bottom and will have a open layout. I want to know what kind of fish I could keep. I have been searching the site lots lately and I have found many beautiful colorful fish that are 10 inches and bigger. I would rather have 3-5 large fish then a bunch of little. I just don't know some names and who wont kill each other. Thanks for any suggestions!
