I would need payment ahead of time and can't do it until the weekend, but I'm well liked by the owner and may be able to get you a discount on the fish.
Friday afternoon would be good, PM me when you figure out what you'd like to do. Last time I was there they had two or three datnoids left that were roughly 3-4" if memory serves me right. I could be wrong on the size.
Like I said, PM me with what you'd like to do. I'll be heading by their shop Friday afternoon but have nowhere to store the dat's. Could have them placed in an O2 pumped bag and float them in my large tank, which would probably let them last about a day.
