I agree that sand looks good in a reef tank.I have 60lbs of CaribSea Fiji Pink on order for my 75G 36 x 24 x 20. I hoping that'll give me a little more that 2". I plan on having a wrasse dominated tank with corals. Not necessarily sand-burying wrasse. Aesthetically, it looks good.
I don't think I could go bare bottom either (I'm still talking about tanks ). A reef tank feels like it needs sand; however, I have seen several bare bottom tanks that looked killer. It's not for me.I agree that sand looks good in a reef tank.
I thought about going batter bottom but could not do it in the end.
I wound up getting the yellow flanked fairy wrasse and the red head salon fairy wrasse.
Both of them are in my holding tank with the scopia tang and cinnamon clown.
