I had fresh water tank for about 8 years, which imo is 10x better and easier. True, you can't get as good of fish in fresh water in terms of color, but you can get awesome looking african cichlids which have awesome color if you know which kind of fish to buy. Salt water vs. fresh water = You have to clean salt water tanks about once every 2 weeks, with my fresh water tank you only have to gravel vacum about once every 3 months, and water change. Not to mention fresh water fish are about 1/5 of the costs of salt water, although I have no good salt water advice for you, my advice is go fresh water, unless you are really into what you're doing and want to dedicate 1-3 hours every 2 weeks cleaning gravel and adding new salt water, good luck have fun...Note - African cichlids are very very agressive and faught all the time cuz they are hard core territorial, that was great entertainment in itself, throw a gold fish in there, BOOM dead in less then a minute.
