The creep tiles don't exist in the Installation tileset. Well, they do, but they are black like null tiles; they don't look like creep.
Scroll down on the tileset a little bit and you'll see this tile:
This tile is buildable, and therefore creep-able, though when the creep appears it will be black as mentioned above.
I don't know if larva actually survive on it, but it seems reasonable enough to me. You'll just have to try it. Lay a bunch of thouse tiles somewhere and put a hatchery on them.
