I am avid freshwater guy but really itching to start a saltwater tank. Been debating on FOWL tank or possibly a clown invert type tank. I would dedicate either a 90 gallon or 4 foot 120 gallon tank to this project. How much lighting will be needed for something 20-24 inch tall? What is best anemone for clowns to host? Do I need to stay with only one species of clown per tank and if so what species is most communal? I would love to have a small school of 4-6 clowns and possibly 1 larger open water swimming fish. I know most basics for salt but the lighting is a major question especially since new LED etc. Any advice thanks.
