Its an eastern milk. Many of them will give a hard time as captive species. Even the CB ones I've rarely seen are supposedly hard to keep. They can be very picky eaters, there is no one thing that they will definatly mow on. Most people have success feeding them small lizards/skinks.
If you're going to keep it. I'd suggest a very strict quarantine. Keep it as far as possible from your collection. If you have other CB animals quarantined, keep him away from them as well. Its highly likely he has internal parasites or something else kicking around. Taking him to the vet to get everything worked over is a must if you want to fully incorporate him into your collection.
Hes a lovely looking fellow. I dont know hes worth the trouble he may cause you though lol.
