So, some of my favorite fish include panther groupers, spotted sweetlips and the hippo tang. I know they all I need 150+ gallon tanks when they are old, but what are your opinions are growing these three fish in a 90 gallon 4 foot tank? Besides, the sweetlips, I 100% prefer the juvenile version any ways. My LFS has told me they will let me trade in my big one for a younger one. They also told me they have had their hippo in a 90 for 5 years and he is still not too big. How long will the sweetlips and grouper take to outgrow the tank? Thanks
