I would rather buy a festae from a trusted board member than an online vendor. Somehow, I feel that an online vendor is gonna send you a uro 9 times out of 10. www.predatoryfish.net has a number of commercial fish sellers who are board members & will ship.
So if I were interested in buying, that would be the first place I check out. That is of course, if you don't find any reputable board members here that are selling festae. If you want specific members you would like to contact over there private message me and I'll get back to you asap.
