I had a dim hope you'd correct me, Michael, and you came through. Your data quality is superb as always. Do you know if yours is the biggest (to your knowledge) in captivity? She is 35" = 89 cm, and 14 years now then, probably 16-17 kg at least.

Looks like if you submitted your data to FishBase, you clearly have a much bigger specimen. Even far bigger by weight than the FWR's ones.
