It's so cool to see these loaches picking out a spot to retire to at night. Mine have different crevices in the driftwood and rocks that they go to when the light's out.
I can't wait to get this thing going... I think I am going to go to OSH tonight( I need a new PC bulb for my 10gal anyway) and start trying to piece together my powerhead/sponge filter PC tubes.
I am also debating whether to do some Great stuff hardscaping as well...
