How Big Do Fry Need To Be To Be Sold?

[-FighterFishh]

I have about 10 platy fry in my tank and I was wondering what size I should sell them/give them away at? They're at about 0.5cm now.
Thank you!

I'd probably wait until they are around 1", as when they are tiny they are really sensitive to changes in water conditions.

My LFS will take fish which are only 3+ cm in length, but I have sold them from 2 cm privately.

If you can get the fish into decent water at the other end, the buyer's home, you can sell newborn fish. New fry are not particularly picky about water and grow well in a wide variety of conditions as long as you do frequent water changes. The real limit on what can be sold is what people are willing to take. For line bred fish that show almost no variation in the fry, I have seen ads on places like Aquabid where people were selling very young fry. They showed a picture of an adult and simply said that the fish in the picture was the parent. Often they also show a picture of the fry and it is the typical nondescript newborn looking fry but carries a label of "what you are buying".
If it is a fish in demand, it sells well even at that age. Typical livebearers ship far better when they are young than they do when they are mature. I have bought fish at local club auctions that were so small I couldn't find them in the bag and had a hard time finding them once I released them into their home. A month later, after feeding a seemingly empty tank and doing a few water changes, I found some beautiful Heterandria formosa in that tank. The colony that includes these fish is derived from that seemingly empty bag.
