What is one thing you would change about marine fish/marine fishkeeping?

I'll admit, I get so disheartened by the high prices on marine fish! I guess they can't be as relatively cheap as freshwater fish are, though, can they.

I wish saltwater fish could be more easily bred in captivity.

I also wish that there wasn't so any myths around keeping saltwater fish. I mean, there's a fair amount of myths surrounding freshwater fish as well but I think there's more around saltwater. I think I might start a thread about debunking saltwater myths
