I want to make a live bait tank for my boat. Want to keep the little fellows alive, and healthy, until I can feed them to the big ones. Found a youtube video on making one, fairly simple. I need an aerator though, battery operated. I think fish tank stores would be the best bet to find one, if they exist over here.
I know we have had discussions before but can't find them so any help appreciated

The proper function of man is to live, not to exist. I shall not waste my days in trying to prolong them. I shall use my time.
