EC, i tip my hat again to yr skill & experience. thank you for sharing this piece of living art with all of us. it's a real delight to look at.
i’m curious to ask if you’ve considered adding sponges to the menagerie?? when i first restarted my tank back in feb-2018, i purposefully didn’t hookup a skimmer because i wanted to further encourage all manner of microfauna & invert life from the live rock that seeded my tank reboot. lots of pineapple sponges and random tunicates among other critters.
i took my time letting the tank cycle (the full summer of 2018), and in the fall, i started added the more common macros to my tank:
Cladophora,
Caulerpa,
Halimeda,
Ulva,
Penicillus,
Udotea &
Gracilaria. I'm looking forward to adding red macros to really add color. the
Gracilaria didn't make it cuz i was previously running my lights too blue, i think.
in the meantime, i took a chance on a sponge ... or two ... or three ... or four, hehe. mostly
Amphimedon or
Ptilocaulis tree sponges. they've done quite well, or at least they're pretty stable in shape, color and form.

in august this year, i picked up a
Teichaxinella ("orange ruffled sponge" per LA/DD), and it has been doing well for me, much to my delight, since it's considered (?) a more delicate NPS sponge. i took a chance on it to test my skill-set. (original LA/DD image below)

if that
Teichaxinella holds up well for the next several months, i'll be further encouraged to try the likes of sea fans or a spider sponge, maybe even a carnation coral. thank you for the inspiration!
