Speaking of opposite tanks...
A couple of months ago I decided to clean up the sump and I removed a couple of rocks I had there.
One of them was in the dark and had some corals attached.
I placed the 2 rocks in a small tank and I only added the head of an old filter for water movement. No light, no heater, the tank is near a windows and that's the light it gets.
I quite like this little tank because of its simplicity. I add ro water once per week and I made 2 water changes since I set it up.
