Hey everyone. I must say this is the best forum i have found so far. I have a 20 gallon tank and would like to turn it into a SW tank. I have had freshwater before and I currently have a 90gal fresh water. From reading i think the most fish I could put in a 20 gallon is about 4. I am wanting to add LR as well I would really like to create a tank where there is alot more LR and Coral in the back. I know 20 gal is kinda small for SW but I would like to start off small to learn everything and then eventually convert my 90gal into a SW tank. What all do i need to get started and any suggestions on fish and LR/Coral?
