Here's my old 60 gal tank that's been running about 5 years, largely neglected until a few months ago. It's got mostly new corals/livestock - added within the last 3 months up to a week ago. Only two corals with skeletons - monti cap, and alveopora - to tell me by dying if my tank is out of balance.
Everything is small right now, but there's a few things I like about it.
It's backlit by sunlight for a couple of hours very early in the morning, and benefits from a bright window the rest of the day. I think this allows me to get by on cheaper lighting.
It also allows me to run a fuge with macro/micro algae in it in the windowsill that gets blasted with direct sun most of the day. This is what I attribute my lack of algae issues to. (I use tap water and a skimmer that doesn't work half the time)
On the left I have Disco Cave.
Those green shrooms are freaking immortal, by the way. They are the descendents of a single frag in a Tupperware container that I shattered onto concrete from a 2nd story balcony. Also months of broken lights, and 5 years of general tank neglect. They now have multiplied to a couple of dozen of those guys.
My "weed coral" guilty pleasure: I just love the sun on these yellow polyps.
Runner-up "weed coral" guilty pleasure: my gsp, that I built a tree for. Can't wait for the plugs to take over.
In the middle is Zoa Valley. Had to cure two frags of zoa pox (why can I only spot that after I buy the frags?) LFS equivalent of beer goggles I guess.
And then the right has Ric and Rhod Boulder.
In between, some random palys, a kenya tree, mushroom leather, and pulsing xenia.
Maybe one day it'll grow into a full impressive display like some in here.
