I used t do salt water, had a 55 gallon, 48 gallon, etc. We started with live rock and damels to start the cycle. You'll love it when its all ready to go, just make sure of your PH and salt level and keep the tank clean!
We had clown fish, anemones, live coral, cleaner shrimp, bermuda angel (Sam, he was a character, if we didn't hand feed him his prawn fast enough he would spit water out at us, lol)yellow tang and I forget what else. If we didn't have to move to an apt at the time we would still have our tanks!
