That is a lot of tads at one time for a private hobbyist. The most I've had at the same time is 45. I am sure there are private breeders that keep more but 80 tads takes up a lot of room and time. The good thing is that they are bigger species and thus hardier. I saw that you were keeping Bakhuis. I've been mulling around the idea of keeping a pair of those for years. They are suppose to be one of the smaller Tincs.
