I'm wondering if there's a list of fish by common, uncommon, or rare. What I mean is, for example, you usually get fruitfish and/or spotanus in common eggs so I would class them as common. Leaffish would be a step up, making them uncommon because you can breed them from common fish, while groupers would have to be bred from uncommon fish, making them rare (again, this is all by my thinking ).
I need to clear outmy tanks, but I don't want to unknowingly get rid of an uncommon or rare fish.
