Recently, as in about a month ago, I got a small, 10-gallon freshwater aquarium. I love it so much, and I was wondering about getting a 29-gallon marine reef aquarium. Clownfish have been my favorites since I was only 2 years old. I want some tips on keeping saltwater fish. I don't think I will be able to get the aquarium for several months, possibly a year, but I'm just curious as to how hard it is to keep them.
