I haven't posted in a while since Im kinda out of the hobby for now, but my friend has a Clown fish in 1 20G tank in his office in NJ. ANyway due to the recent storm they have lost power. There has been no heat, or circulation in the tank since Sat night. The temperature in the office is 51 right now. I know he can get a battery operated air pump, but is it even worth it? Will aeration help any after 2 days, and with a temp that low? Any way to heat it up? There is also no hot water in the office.
