ZOO YORK 207;1201675; said:It's like I said before it definatly isn't a african knife. notopterus notopterus do not have a dorsal fin.
do some research before making stupid comments...
the african knife is not a notopterus notopterus... its a Xenomystus nigri
notopterus notopterus is an asian and all the websites seem to agree that they can reach a 24" size but im sure it wont in a tank...
