Finally got the windows back open as it got into the 50's last night. That's not good for tank inhabitants. Water temp was 83 without the lights on (up to 85 while they were on) and this a.m. was 78. My leather refuses to open tonight to eat and I lost my 5" tang. Finally found him stuck to the pump. Anyone interested in the other livestock? I already have a taker for the lights and live rock. I'm ready to give up.
