Sometimes I have leftover minnows nd don't want to fool with a whole bait tank setup. How long will minnows survive in a 5 gallon bucket if I keep a small air pump running? Say it is 2 or 3 dozen in about 3 gallons of water. I'll keep it cool.

I'm not asking about building some bait tank - just wondering if minnows can make it more than 24 to 48 hours in a bucket with a bubbler running.

Will a pinch of goldfish food keep em living longer?
