I fully understand it's not wise to misrepresent your self or your property to insureance companies. I was just stating that when most insurance agents hear the word "Shark", and they may naturally think - big blood -thirsty fish that may eat people. So they may automatically say No, or look at you like you've lost your mind. Be perpared to fully explain things to them
Generally most insurances agents just want to know if the species is potentially dangerous to people visiting your home(opening you up for a law-suite if something does happen). If you plan to let people enter the tank/pond with the shark or not.
But still the best thing to do is to ask your insurance agent - if it would make a bit of difference in you home insurance, before you get the shark. But plan to explain in detail - about the species your planning on keeping. and about the tank or pond you plan on keeping it in.
Also note - as I've said before - INDOOR Pond, Perferably in a room with heat & A/C - this way it be much easier to maintain a more constant water temp for the pond.
