I’d like to get opinions about how easy or how difficult it would be to maintain different types of tropical seaweed in a saltwater aquarium. I know that most people keep aquariums for fish and other animal life. But my interest in seaweed was sparked when I went to the beach here in Honolulu and came upon a spot with a mass of different types of seaweed. The variety was amazing – lots of different colors and different shapes. I thought it would be great if they would grow in an aquarium. But I don't have any experience in saltwater aquariums. Should I try it?
