Any one have a spiny box puffer in an aquarium with cool aquascaping. Due to it not being coral, snail & invert friendly , it limits what you can do to make the tank look cool with just him and a handful of fish.
Check out @siggy 's scape in his new tank. Really interesting structure. I look at it the same way I do an all white room in a beautiful home. Texture plays a big part of the visual interest.
While it can be sort of plain with rock only, I like fowlr's. Create caves and overhangs with rock and although I don't like it, there is some nice artificial corals being made today. You can also use some coral skeletons as decor, bleach it and use prime to dechlor when it gets grimy and algae covered. Although he may tear up the macro, using some decorative live macro algae also works well and is inexpensive.
