Oh definitely! It may just be your tetras and only your tetras! What I've learned about cories is that once they're acclimated they're terribly hard to kill! Out of the 16 Cories I have bought, 3 have died, all from stupid fin rot, which they had from the store. The first three I have ever bought have seen my other fish get ich, fungus, fin rot, and general sickness..yet are here still today. They've seen more diseases than most fish, yet have never gotten any themselves! Tetra's are more prone to ich, from what I've seen. But for your final question...nope. It'll attack all the fish, but the ones strong enough to fight it off won't get it. Bettas and cories from what I've seen are very good at fighting and resisting ich.
