...the baby racers I've kept love frogs. Theyre also know to eat small lizards, minnows, and insects. I'd start with offering lizard or frog scented pinks for a meal. Id continue to offer pinks or minnows and if you cant switch him over soon Id consider releasing him. Adult racers are very active and will require a cage with a lot of floor space. They'd also benefit from full spectrum lighting and a source of ventral heat as they are diurnal. They definitely need a hide box or thick substrate in which they can hide. Good luck and Id love to see some pics.
