Ok so right now I have a 75 gallon tank with a 5 inch female jag and 6 inch oscar. I also have a 2 inch male salvini and red texas. They obviously arent all staying and I eventually just want one fish if i keep my current setup . I aslo have considered getting rid of all of them and getting a few Jack Dempsey and a red devil or Salvini. What would look best for show off in a 75 gallon Im going for looks what fish should I get,keep,or put in there im really stuck
