yes musho you can.....You can use uncured live rock at the beginning of a tank set-up to cycle your tank. The cycling process cures your rock while breeding beneficial bacteria.

it not that 2 clowns are no good, its that a 20 gallon is not good enough for 2 clowns.

well to add to my reply, technically clowns shouldnt really be in anything less that 30 gallons. We did have our 2 in a 20 gallon and had no problems, but it doesnt mean that every 20 gallon is going to be like this. Just like everyone is different, every tank is different. And what works for us may not work for you. Just keep that in mind ok.
