Aquascape help desired

[MrPiGuy]

I have a section of my aquascape I feel could be a lot better. Any advice on what to do would be greatly appreciated. I’d like to take the big rock under the arch and break it up and add it back in to compliment the space under the arch. No idea how though… pic attached for reference. The big rock I’m referring to is difficult to see but is poking out a little bit under the arch on the left.

You could just bring that rock on the left forward. Fish love (love, love) caves, crevies, nooks, crannies, overhangs, etc. Anywhere they can zip around and explore = happy fish!
