I've heard it said that if you can keep African Cichlids, you can pretty much keep anything. I've recently taken an interest in saltwater, but have no experience in it. I'm thinking about a 30+ gallon tank, looking for a good compromise between dilution factor(size) to keep the difficulty down and cost. Money is something I don't have coming out of my ears, but my car is about to be paid off which will lighten the load considerably. I have no time frame and plan to learn everything I can before I spend a cent on a tank or equipment. I'd love suggestions on good starter sizes, filtration, substrates, everything that has and hasn't worked for you.
