In my tenure at Rainforest Cafe I had the particular discomfort of having to work with sweet lips…
Are you looking for a fish that will exhibit some real personality? Follow you around the tank? Maybe even let you pet it?
Then forget the sweetlips. They're basically a stomach with fins.
Did you want something dainty and elegant? something that's a good mix of color and activity?
Forget it, the vast majority of sweetlips lose 80% of their color in the first year. (I think the clown or striped is the only exception)
Did you want a mellow, even tempered fish that'd be laid back and easy to care for?
ok, they got that one thing going for them, but you can see my point.
There's a small list I keep in my head of fish that I have no earthly clue why people like them.
Right alongside look-downs, pilot jacks, and pompano… are sweetlips…
They're big, obnoxious, eat everything and anything they think might possibly maybe be food (they would bite at our fingers, goggles, wet suits, exposed skin, hair, etc to no end… but not only that, but the tank decorations too, as if the 3 years it'd been there suddenly turned it into food) and are general dicks to be around (if you were another fish)
If you want one go ahead, I see no reason to keep one.
A 300 tank is about the least you should realistically do, they are rather active and they need the water to dilute their tremendous waste.
Most species get to about 1.5' in captivity.
