Depending on what direction you go with corals, I think there is way too much emphasizes put on the rock work in this hobby, or aquascaping.
Of course that is just my opinion, but take a look at this tank and see if you see any rock at all?
This tank is 50 gallons. I don't mean to hijack, I just wanted to point out I think you have done a fine job with your rock work.
The coral placement will be key.
