Yet another reason fish make great pets - they don't cause fires!
Well, here's my fish-fire story. First moved out of parents house, rented an old rowhouse in Baltimore with two of my friends, one of whom was also into aquariums. We set up an awesome fish room! Unfortunately, we did not take the dangers of electricity seriously at the time. Too many things plugged into one outlet, through a cheap multi-outlet extension cord.
One day a couple months later, during a work day, the cord caught fire. Cord burned its way up to the hood of a tank, burned up the plastic hood and all the non-wet parts of a hob
filter. All the burning stuff fell into the tank and was put out. the heat also got intense enough to crack and break the glass, 29 gallons of water mostly spilled out, prolly kept the carpet from catching fire. Right next to a wall with cheap 1970's panelling, big scorch mark on the panel, but it didn't catch. At some point the fire put itself out, luckily. Very much smoke damage (have you ever seen plastic burn? heavy, stinky, nasty black smoke.) Wintertime, no smoke got out, fire dept. never called. We never got caught by the landlord! The place was rather a hole to begin with, so it was in the lease that if we wanted to upgrade stuff, we could call, get stuff approved, and deduct from rent. we had to super-clean the house, replace ceiling tiles, and paint the whole place. didn't cost us anything but a lot of hard work!
So, Fish CAN cause a fire! Though I know it was our own stupid fault, really.
A couple miracle fish survived, the tank broke most of the way, but there was maybe 2 inches of water left. A keyhole cichlid and some corys made it through!
Oh yeah, it was my roomies fault not mine.
