Agreed too and for a purpose.
Actually a close up would have been better. There are lots of crevices, caves , overhangs, hiding places and even a tunnel. Inside the branching structure is like a maze. Most of these can't be seen in the posted pics.
It's going to be a fish only tank initially, let it mature and maybe add some carefully selected LPS in the future, like over a year at least, to encrust most of the rockwork to get that natural look but with the structure already there. Some nice neon trumpets, ducans, a sun coral add a centre piece nem would be the end goal and I'd be pleased as punch if I could manage it. Simple plan to follow over the years hopefully.
Fishwise, 6 or 7 only and they all must meet my requirements, peaceful, not silly prices and MUST serve a purpose including standing out strikingly obvious against 2 purposefully blacked out panes of the tank. I have a fairly short list and could add a couple more.
2 x Percula Clowns (Common clowns even depending on price).
1 x Yellow Coris Wrasse (Halichoeres Chrysus) OR Canary Top Wrasse (Halichoeres Leucoxanthus).
1 x Purple Firefish (Nemateleotris Decora).
1 x Tailspot Blenny (Ecsenius Stigmatua).
1 x African Flameback Angel (Centropyge Acanthops).
Nothing is set in stone but the list above would be nice for me, ideal so to say. Because of the depth it needs to be visually active and I think this selection could work with surface/midwater/rocks and surfaces and sand level activity taken into account. The Angel is the issue both for fish only tank and the proposed LPS additions later but I would take the risk.
I have all the time in the world at the moment and no plans to get it wet soon. No particular reason, just that I can and rather not rush.
