I know it is different with every spawn & with every fry for that matter, but is there an average age that you should start jarring fry? My fry are about 5wks old and I have at least one that keeps chasing and nipping at the others. Should I pull the one now or wait?
One other question about the fry, I don't really know how you determine their age. Is it the day they are put in the egg nest, when they start hanging vertically, or when they start free swimming? Just an example here, but if I had a spawn start on 4/18 (egg put in nest), they hatch and are hanging on 4/20, and started free swimming on 4/23 how old would they be today (4/25)?
