Looks good Eric. You need the SWC led light fixture I purchased for it originally.
. No overheating then.
With the bare bottom, I would say just snails are required. Dont recall the name but the turbo,s that flip themselves over is the way to go, IMO. They have the black feet. Keep my 20g fairly clean.
I have some red scarlets and they pick at stuff but I dont think contribute much in the clean up way. I believe I still have some that are well over 5 or 6 yrs old though. I also have a couple smaller emeralds to help with the {Mikey bubble algae},
. Dont think they do to much either.
My best clean up item is the siphon hose on water change day, both for the bare bottom and crap/algae on the rock.
