I go to my lfs weekly to see if they get anything different and finally after a yr or so I seen they had one of these. It's only about 3-4 in now , just wondering how long I would have to grow it out b4 I put it in my big tank?
Depends on the species, I got an auchenoglanis wittei giraffe cat in April 2010 when it was 2 1/2" long, it's now 19-20". Research shows that they'll ultimately reach around 30". The more common species-auchenoglanis occidentalis, grow to 3' or so, hope this helps...
Yep. IME and from what I read, the biggest ones in that genus (that grow to about 3') gain roughly a foot a year first year or two. They will slow down noticeably with years.
ID-ing species in that genus is far from easy, BTW.
They grow a little slower than the fast cats like rtc and nigers etc. but not much, about 2" a month until they reach about 20" and then their growth will start to slow. Great cats. One of my fab I've ever kept.
