Look at it this way - he'll be te one taking care of it, right? So you get to just observe it for the most part! What you will find is that they are incredibly captivating and interesting animals. I love them, but can't build a tank that I think is large enough for the species I want. Space limitations, ::sigh::
Anyway, I'd say let him do it. Observe them, and make your decisions anout them then.
I am highly prized for my meat. :eb:
