Ebony male chinchilla

I have a male chinchilla that is for sale. He loves his raisins. He is about 3 years old. Just downsizing. We have named him Gunther but that can be changed. He is an ebony color which means he is all black. Not good with other males unless it’s a baby and good with females. He has a small rehoming fee of $100. Nothing included. Prefer someone that has experience with chinchillas or at least done their research
