Josh, I have a 30gal clear plastic tote about 10 bucks, I put a dual out put aquarium pump on it and got a filter pump for 100 gal aquarium that takes 2 charcoal filters on it. Have some minnows that have been in there over a month. I never feed them anything. Check your local thrift stores ( goodwill, salvation army ) will find something cheap. Fill what ever you are going to use and get some clorout or what ever they call it from WM if you have to use tap water and let it circulate for a little while before adding minnows after that just add make up water and it does not seem to affect them. Keep them as cool as possible. I'm fortunate to have a shop I can keep mine in.
