Okay guys. Need your help. My 55g is under lock and key. But my kid found a way to feed two cookies to my pretties. How, have an idea. But not 100 percent. My son is mentally disabled. So he does not understand the concept of look but do not touch. I am thinking of getting a small tank for him and get a couple of fishes. What fish out there would be able to handle a earthquake, ice storm blizzard, tornado, hurricane, atomic blast and any other child disaster?
