no doubt any marine life will definitely do better in the ocean. Does that mean we all should quit the hobby???? I guess we all try as best as possible to recreate natural ocean conditions in our systems to successfully keep any type of marine life. Thats why research is a great thing and is exactly what i'm trying to do i maybe wrong but just thinking of leaving them in the ocean is kind of a contradicting ourselves. And by the way my system is 2 years old.
