^Note my last living frag and few snails...)

I’ve had my nano cube up for three years, and a recent addition of an urchin caused all of my inverts to be eaten over night... (It’s pretty bad). Now that these guys are out, I would like to renovate the tank as I will be starting with barely any coral.

I wish to add: More hiding spots for fish, More places for coral

Hmm... never heard of this. Which invertebrates? Seems unlikely the urchin was the cause.

It was a duo of a Caribbean Purple Urchin and a Pencil, they ate most of the coral and about 5 snails

Got it. That seems possible. How many gallons is the tank and how many pounds of rock?

If you want aquascaping ideas the best advice is to look at lots of tanks. It is hard for me in the picture to pick the shapes of the rocks from the stack. In general I like to keep the highest point about 2/3 the height of the tank. I like to keep some open area under to allow good flow throughout.

Due to the size of the tank, I would move to smaller pieces of rock, either by breaking some of those up or by adding different pieces. You can then manipulate the shapes a lot easier, while also keeping the perspective of a piece of the ocean in a smaller tank. I don't think you are going to be able to change much with a couple of large rocks like you currently have.
