Does anyone have any recommendations for how to "beautify" a fish only tank? I have a number of fish that don't play well with coral, and so I've been limited to live rock on a white sand substrate. The fish can be quite pretty to look at, but that only gets me so far when the tank is comprised of a mix of whites and browns, with the occasional green from algae buildup. For reference, I have a dog face puffer, a princess parrot, an angelfish, a tomato clown, and a blue tang. Any tips would be greatly appreciated.
