Just when you sit back and think that all in the tank is rosey, something comes and slaps you in the kisser. Ive been away at the OH's parents for a few days, came back today and found the tank half empty and water all over the floor.
Mega leak from the bottom of the tank, at the front seam, and the tank was almost empty. I have lost 5 fish, including 2 of my cory's. Ive done an emergency seal job on the seam with some sealant, and refilled the tank, but I dont know if the heater is still working because it hasnt come on since I refilled the tank.
Anyway I can keep the water at a decent temperature for the fish overnight? I thought of covering it with a duvet - is that worth doing?
