yeah it could- could also offer more places to mount corals, but the main thing is for fish to hide, as well as getting enough flow throughout your tankWhy do you suggest more caves? Are all of the holes in and around the rocks not enough? Also there are small rocks making footers under the big rocks at the bottom to help make “Scotty” the engineer goby, happy. Or are you saying more caves would be prettier?
I'm open to suggestions, and have a good bit more rock to play with, I just didn’t want to make it too busy.
