Do you mean AES and BLOWFISH?
No, he means AES and Twofish.
Blowfish is a Fiestel network cipher designed by Bruce Schneier. It was examined and found to have certain weak keys that can reduce the complexity of some theoretical cryptanalytic attacks, although no one has found a way to exploit the weak keys.
Twofish is a Fiestel network cipher designed by Bruce Schneier, John Kelsey, Doug Whiting, David Wagner, Chris Hall, and Niels Ferguson. It uses some of Schneier's ideas from Blowfish, but it is not the same algorithm. Twofish was submitted to the NIST as one of several algorithms intended to replace DES. Twofish was not selected, Rijndael was selected instead and became AES.
To my knowledge, there has been no successful cryptanalytic attack against Twofish.
