They could get it, ich is a fish based parasite and will infect any host fish that the larva come in contact with. There are some that are more ich resistant, but if it gets on the fish in even the tiniest bit, once you re-introduce the hippo back into the tank, it'll get ich again. There are several stages of the parasite, and because of this, the main display tank will need to be completely fish-less for about 5-6 weeks. This is the only sure way to rid it of any stage of ich.
