I know this is an old thread but since the majority of the people in here are still active I thought I'd bump it back up with a video of my weeksi that I took a year ago when I first got it.

Nice to see the Weeksii thread. My big boy is turning 14 years old. Size wise you can see him touching both front and back on a 24” wide tank. This is his last week in the cramped 180. 255 next week
He lived all 14 years in the 180? I feared my polys would get stunted long term in my 225. That relieves me lolNice to see the Weeksii thread. My big boy is turning 14 years old.

actually he has lived half his life so far in a 150 g. (58”X26“WX 24”). I have grown out several 20”+ bichirs in this set up. Never missing a weekly 80+% W/C
There was someone who grew out a 28"-30" congi inside of a 180g (6x2x2) in 8 years. Tank size isn't usually why bichirs get stunted though.
I think it has to do with genetics as well. Definitely multiple factors when it comes to growing out bichirs to big size. Generally what I’ve seen is most lower jaw bichirs grown out in captivity get “stuck” at 16”-18” or so.
Tail is bent against the glass, I will have to take him out for a better pic but 24”
