I stare at my rocks, watching things appear and disappear. Month and a half old rock from the gulf, lots of life growing, receding, appearing out of no where! I saw a super tiny snail yesterday that I definately did not put in there. Looked like a little bity cerith! I'd say 2+ hours of watching a day, 5-10 mins of top off time ( moved the auto top off to the new sump, hose is too short to reach the resevior atm) and maybe 10 mins a day checking the quarantine tank (more time watching the fire fish hide in his pvc and peep at me, or swim boldly up to the glass to flick his fin).
