Fish Aficionado
Convicts aren't always 5", my adult female was only 2.5"
I'd say a pangasius in a 5ft with three plecs and all those other fish too would be vastly overstocked anyway, even if it didn't grow any bigger (unlikely). You'd need at least a 180g for the three plecs if they were all the same species, just for them to have enough territory. Obviously in a 180g you'd have room for other middle/top level fish though lol - not just the plecs!
But I'd rehome that pangasius while you can - if you can. Once it hits 12-18" it'll be nigh on impossible to find it a new home and euthanasia might have to become an option once he got even bigger. Try finding numbers for local public aquariums (if there are any near you?). They might have room for him?
In his other post he said his 7' pangasius catfish ate his 5' female convict
