Second feeding with big mullet. Wels ignores the dinner bell and ignores the big mullet piece when it is dumped on its head:
idk just a general question lol ik they get 8-12 feet in the wild but usually there’s a big difference in captivity but idk what the exact definition of captivity isTBH I don't know and never searched out this info. It seems peers experienced with wels expect at least 8ft in their (human) average keeping time / remaining lifetime (20-40 years?). Wels can live a century or a couple, so any answer to this question would be quite a "soft" number.
Captivity also varies. Fish tank, above ground pond, Public Aquarium - I understand. But is a private 10 acre lake, or a totally unmanaged, wild 100 acre lake a captivity?
