I am also really into aquariums and fish from around the world. I only have two aquariums set up currently. Both are fresh water setups with beutiful plants, angelfish, assorted western hemisphere cichlids, and assorted catfish from the world. Hopefully i get the chance to set up a saltwater aquarium. The first and last saltwater aquarium i tried my hand at was taken over by ecto-parasites which killed most of the fish.
Saltwater fish are SO beautiful and so vivdly colored, let alone the environment they come from.
I don't recomend setting up one of these types of tanks unless you are willing to put some serious time and money into it though.
