How big will my brown knife get

  • We are currently upgrading MFK. thanks! -neo
They're probably one of the smallest of the knifefish, very good for us who have limited space :D and want one. Got any pix of yours?
 
yeah ill post some i just need to take some
 
they grow slow max out at 8-9
 
my african knife is only about 8 inches at best. i've had him a few years and i keep up with the tank. he feeds on a mix of sinking cichlid pellets, bloodworms, flakes, and i swear he has eaten a few tetras.
 
I got an ABK in like February and I didn't measure him but he looks the exact same size so I don't think they are fast growers
 
I've had mine for 6 months and he's maybe grown 1.5". Around 4-5" when I got him, probably 6" now. He used to hide a lot but now he's out swimming all the time, he gets mostly sinking cichlid pellets but he really likes the Ken's soft & moist ones.
 
;) Agree w/ the others. Definitely one of the slower growers. What size tank & is he alone? "T"
 
Mine is in a 75G growout (recently upgraded from a 55G) with 2 senegal polys, 5 jurupari, 2 festivums, and 2 red fin cigar sharks. The sharks are headed to the adult tank soon. The festivums and juru's are all around 4" or so and the sens and knife are 6" or so. I do 50% weekly w/c on all my tanks and my nitrates don't get over 15 ever. I think they're just relatively slow growers (the juruparis too; this is a long term growout situation).
