You are paying for all the work it takes to get good bloodlines when you buy from Lotsoffish. He is a friend of mine and we trade fish all the time. He has 80 tanks in his fish room and his buddy Conrad has a small fortune in his set up. They won't even keep a fish if there is one small defect. That's why his prices go so high on his auctions. You know you are getting extremely high quality fish. Plus with over 40 years experience, I think he knows what he is doing. I'm not a guppy fan ( they're cool looking just not my thing) but every time I see his tanks in person I have to stare for a while at them. I feel like a kid in a candy store.
