My first holding fish was a yellow lab and was holding at a size of just under two inches. I recently had another one about the same size also holding. Now some of the fry from my first clutch are as big as their mother, with one even bigger though none of them have started holding. I have read on this site that age doesn't matter but just the size of the fish though none of my fry (well I guess they are all grown up now and I have to learn to let go and accept that they are adult fish) have bred yet.
