I just left for a week and tried a new method. I set up a 55 gallon tank and filled it with feeders(2 weeks before I left). Treated them with prazipro, high temps, and salt. I had a friend who could come over twice during the week I was gone. He likes fish, but is not a fish keeper. So I told him to take a net full of feeders for each tank when he came over.
My theory is that feeders will not go bad in the tank like a perpared food can if over fed. I am not worried about fat fish or hungry fish. I am worried about bad water quality.
