With most sunfishes of the genus Lepomis, I use freshly hatched brine shrimp (BS) as the sole food for the first 14 days after they swim up. After 14 days they are co-fed powdered feed and BS until 21 days when everything is going very well and up to 28 days when higher survival desired. Below is most recent and relevant article to Redear rearing.
