So, you are going for more coral or more fishes' tank concept?
Just went through your tank's update, very unique rock scaping, well done. Provide more space for fishes to swim around. Wanna to consider to get a school of BE? kinda interesting to see them swim in gp.
If you going for coral tank, then maybe can add more colourful stuff, thing like.. mushroom, zoa , or LPS like blasto (usually small and easy to keep, IMO), or all soft coral fill with many many red,pink, orange cauliflower, wasai!!!
So envy you can keep tourch and hammer, mine can't.. mealt away within a month
