Thanks for posting this article. This article was more of a profile about Calumma parsonii ssp not a care sheet. There was some good information in this document. However there was a lot of information that was not accurate in this document. One of the big ones was that Calumma parsonii ssp. have short lives and only live for 4 years in the wild and in captivity.
I thought there was some inaccurate information in it too. Its hard to know weather it's worth posting things like this for the good information in them or just skip them.
I think this article is an older article that has outdated information. Most of the information that is off is information that is going to be obvious error to most people that have had experience with Calumma parsonii ssp. I think it is important that people who read this article understand there is outdated information in this article.
