I wouldn't say rivalry; maybe adversaries. From what's been shown, I personally don't see a rivalry between them.

When Tucker told Felix that Locus was at the outpost in Hit and Run, Felix's first instinct was to get the hell out. He IS brave enough to stand up to Locus, but I don't see a genuine rivalry between the two.

Locus seems to be more interested in Wash than Felix, based on how he nearly killed him in Neighborhood Watch and what he said about Wash in his journal entry.
