I bought a 4.5" green terror from a lfs a several weeks ago. When I first got him home he would take Hikari Gold and Spectrum pellets in his mouth and then spit them out. The only thing I could get him to eat was live worms. After trying for a couple of weeks to him nothing but pellets without any success, I finally gave in and went back to live worms. However, now he won't even eat worms. Any suggestions?
