thanks guys. i was stuck between sand or gravel. with crushed coral sand, i would have had a hard time keeping down the pH. This would have worked great if it was for a cichlid or yellow lab tank. The important thing is this, the coral has soo many hiding places, so i can assure that the fish will be happy.
if u want it to really look SW, buffer up the pH and get some RVL cichlids(AKA assorted african cichlids). IMO cardinal tetras are a very FW-looking fish, while cichlids look so out of place in planted tanks and are perfect for SW imitation tanks.
