Man their not kidding about how fast they grow. I would say it's grown almost an inch in two weeks.
Giraffe cat growth rate.

For auchenoglanis occidentalis, I've seen several people state their's reached 2 to 2.5 feet within 2 years. Maximum adult size so far appears to be 59" in the wild.
Beautiful fish that very few people can keep. If I keep only one giant catfish, this will be my choice.

I knew they grew fast but after owning one I can attest to that statement. Will probably outgrow this 220 in two years or sooner.
It will not sustain such a growth rate. Chances are.
Can you, please, reference the max size info? 5' G-cat I've never heard of and I am very skeptical of this number. From all knew they don't exceed 3' in the wild.
Oh I see. Thank you!
I've actually studied this database in some detail and used it extensively for my database in the third link in my signature. There are some glaring errors even in contemporary data, most obviously due to ID errors, like a Zungaro jahu, which is most likely a piraiba in the photo... or 4' juruense catfish, etc.
I generally wouldn't trust those other data too much, the ones listed at the bottom, from "Other methods", etc. which are often from commercial fishermen by memory or by hearsay, rarely from articles and descriptions by scientists and even the latter can be challenged and get challenged, like the fact that wels can reach 16'. In a scientific article from late 1800's, there is a sturgeon in a photo instead of wels! What???
Anyhoo, long story short, my current conviction is show me a 5' g-cat and I will believe. Until then, I think a 3' specimen is a giant, like a 7' human.
We surely can and should disagree too.

We're on the same page. I've found errors in databases, e.g., fish base, which were contradicted by photos of people who went to the Amazon.
There's a study on this specific species (length and weight over around 800 samples) that developed log formula that correlated the two factors (to around 93%.) If we assume the weight is correct, then the "best" predicted length using their formula is 45" (assuming it's male) which makes more sense.
Of course it's easier to 'lose' weight than length (from drying out or poor food supplies), so that is an issue as well, but 45" in the wild makes a lot more sense to me given quoted growth rates in aquariums and the longevity of this fish.
