How do you find the 'Alpha Fry' in a batch of fry. I'm trying to figure out which one it is in my Platy fry, but I don't see any dominance behavior. Any advice??
There might be a small pecking order, and if so, it will most likely be the largest one. As other people said though, there may not be any dominant one because platies are so peaceful. Mine have never showed any pecking order or dominance, they just swim around togather in happiness I you see any chasing eachother, then you just need to look for the the one that chases the others the most.
