Please help, my heater broke, rockslide that nearly killed my betta. i had all of decorations set up perfectly and today they just randomly fell! in the process, Red was nearly killed, good thing that he's fast. but the heater didn't fare so well. all of the electricle stuff on the inside was exposed to the water, not barbecue fish of me when i got the thing out. i spent an hour cleaning the tank of all the shards of glass left behind. but that isn't the emergency, in oklahoma we are having freezing temps and me tank is by a large window. without the heater, the tank gets to 55* with only the light to heat. i have very little money, had to buy meds to help Red heal a bit from swim bladder disorder that he still aint quite healed from. i am currently using a blanket to trap the heat in whilst i go to school. i need an ingenious way to heat the tank untill i gather the $20 for a heater. HELP!!!
