Blowfish is still a really good choice.  

Practical cryptography is unlike many other parts of programming in that
newer is not necessarily better and, as a general tendency, is worse.  A
cipher or implementation of a cipher that's withstood determined analyst
attack for many years will with good reason be considered more
trustworthy than the very latest and most fashionable.

In the area of symmetric ciphers, Blowfish remains among the most tried
and true.
