I have been thinking about getting a new tank probably a 75 gal, maybe a 90 gal not sure yet. I am open to suggestions but I only want to keep a single fish in it. I was thinking about a flowerhorn. What suggestions do you have for a solo fish tank? keep in mind I already have a tank with 2 oscars so I wanna get something different for this one. Thanks and merry fishmas to all!
