I went to the local fish store this weekend to get a filter for my freshwater tank. On the counter of this store the owner had a 20 gallon reef tank, with all sorts of corals and 2 clown fish in it, we got to talking and he said that doing smaller tanks is not harder then doing the larger tanks. Has anyone here done a reef tank before that small? I have an extra 29 gallon tank around, and I was wondering about doing a small reef tank. Unfortunately I don't have the funds for a large tank, and stand, or the room for that matter! So can this be done successfully or is it just a waste of time and money and I should just hold out until I can afford a larger tank and have a place to put it?
