What you do is pick a species. Then you go to the rancher shops and pet auctions and buy the cheap ones. The idea is to help out ranchers and raise the value of creatu that have become worthless. Having saved a fair amout of money I shall be starting with zenerix or tesuri.
Any one want to join?

Edit: so far I have bought 22 zenerix and 2 tesuri, the min zenerix value has been bumped up to 100 tu min. (unless some one just undercut them)

Edit: lost count of the zenerix :p the min value has been bumped to 300 tu
