The way I usually store it is to just squeeze the air out of a zip - top
gallon sized bag and store the bread there on the counter; don't refrigerate
because that just dries baked goods out.
Because if the fish keeps growing, you will need to invest in a much bigger
size aquarium tank that can cost upwards of $ 400 for a 50 -
gallon unit (a 10 -
gallon unit only cost anywhere between $ 10 to $ 30).
