maybe you could arrange it differently, but i've noticed that the tanks i like most are when things are slightly "crowded". as long as the aggressive corals have enough space to grow, less aggressives can actually coexist and bttale for space without harming each other. I see lots of places to put frags with things how it's set up now, but this is the reason i moved up to a little larger tank, more space for me to dump more money into

if you think you'll need to have spots for corals that need higher intensity lighting, then yes. if you are anything like me, you're never happy with it, i am always rearranging my rockwork. i never scrap the whole layout and start over, but when i add some new it never seems to have a spot that's good for it, so 1/3 of the tank gets rearranged. the coral get irritated with all the tinkering but they get over it in a couple days. all i have a softies and LPS tho, so i can't give any advice if you have any SPS in there, which i don't think i saw.
