I just got a noticed from my building management yesterday that they will be putting pesticides all over my apartment to kill all the roaches and I'm concern about my tank and if it will affect or kill my fish because I already spent so much money into it and I don't think that my building would compensate if i lost or if my tank gets poisoned..Does anybody know what I should do?? I was thinking of covering my tank with a blanket or something, but I don't know if that's good.....Thanks.....
