A good example on the growth rate of Polypterus congicus:

Polypterus congicus is recognized as the largest known Polypterus species. The largest wild-caught specimens have been found at 42 inches in length.
Their massive size also reflects on their growth rate. These fish are extremely fast growers for the first 2 years of their life, but they slow down as they grow older.
This is my Polypterus congicus, named Bubba, who I got back in April of 2020:

He is now 16 inches long.
Would you be surprised if I told you I got him at 7 inches?
This photo is of Bubba with his other smaller congicus friend on the day I got him:
(Bubba is the longer one on the right)

As you can see, Bubba's growth was tremendous over the past 9 months.
The other congicus in the photo had a slower growth rate, but he is now pushing 14.5 inches.
With good care, congicus are capable of growing at very fast rates.

Thanks,

How often do you feed? That's impressive growth.

I have an 8" in quarantine right now. Fed him yesterday for the first time since I got him (1 week after the fact). Just going to finish this initial round of deworming (and an additional 2 more cycles) then decide whether I grow him out solo or transfer him into my main tank.

Very cool!
I feed daily with weekly waterchanges.

Sorry for the late response.
