Tyranids + Ork question

[LutherMax]

Orks No. 1 love is killing things, Tyranids No. 1 love is eating things – so they could enjoy a mutually beneficial relationship. Until they start killing / eating each other, that is...

The answer is just no as Tyranids tends to infest anything. In general Feral Orks are most susceptible to infiltration, but sorry Tyranids don't feed their environment, they feed from it and Orks are fungi so they are both very hard to get rid of. Just ask the Ultramarines. They have suffered attacks over and over from Orks and just had Tyranids in their garden. Same with Catachan and Fenris, they both have remnants of Tyranids as their fauna, Tyranids are all take and no give my friend.
