I take my family to the pet store to purchase some fish for our 130 gallon tank, i ask the manager questions, "hey, with these frogs, can i place them in my new tank?" or with these oscars, "can i place them in our tank when i get home", he says "yeah, why woudldnt you be able to." i tell him it's a hand me down tank and we just washed and cleaned it with vinegar and baking soda so it's been cyling with plants for about 2 days, we get home put the oscars in the tank and they die no later than 5 minutes...
