:sad:I woke up to a house in the mid to low 40's this morning. Last night someone messed with the thermostat on the house, no it was not me. They accedently turned it off all the way. My dog sleeps with me so I keep warm and have a Thick blanket, I woke up about 6 am and relized the house was Freezing, so I checked the heat as saw it! I turned it back on, I have an Extra heater in the tank incase one fails, well I woke up the tank was in the upper 60's on the bottom and 70 on the top. I turned the lights on to see the damage. and :sad:... The coral started to open when the lights came on, all looked fine the clam opened, clowns looked fine (at least the ate when I fed them, the dotty back came out and hide agian, seems to have lost some color but had to go to work so could not tell if it was sick from the drop.) every thing seems to be fine except my tiny little tang, froze at the bottom. So I hope when I get home al lthe fish are better and swimming. I am hoping the extra heater helped the tank keep up the heat and glad it did not drop fast like the house did.
