I tried feeding my 3 month old emerald a live fuzzy. He refused all day and I contacted the breeder and he said they like live hopper mice a lot better. I went and got a small hopper mouse, and he ate it immediately. However, 48 hours later he had a very large lump in the middle of his body. The mouse was not much bigger than the circumference of his body, but it was a little larger. I know they're vulnerable to regurgitation, however the breeder said live hopper mice is what he was on before he got to me. I'm nervous now and if he holds this one down, I plan on switching back to live fuzzy but trying more so at night. Any help???
