Redo Existing Aquascape

[kennl]

Hello!

My tank is about three months old and I've realized the initial aquascape is not conducive to the types of corals I'd like to keep long term. I'd like to rework the existing rock, do you have any tips on how to minimize the stress on inhabitants while I go through this process?

Thanks!

What size tank and what fish(es)?

I don't have a ton of space to work with. I have a 40g IM AIO Pro Fusion 2. For fish, I have two clowns and a goby. Perhaps, its best to stick them in another container while I move all the rocks around?
