1. dont put your fish near anything that will catch on fire, like a stove, furnace, or fireplace
2. keep a fire exinguisher in the house so you can douse small fires like cooking fires (no water on grease fire though), and especially in areas where fires are likely to happen
3. dont set things on fire in your house (unless it is IN the fireplace)
4. call the fire department if there is a fire
5. dont light candles near paper (believe me it can happen)
6. IF THERE IS A FOREST FIRE IN YOUR AREA you need to evacuate immidietly, and you can try to save some of your fish, but if youve got big fish like arowana, oscars, etc. then you should leave them.
