Sumatran Rhinoceros Beetle

I love it! Does Chester Zoo focus on keeping and displaying Rhinoceros Beetles?

Are those red runner roaches in there too? escaped livefood i'm presuming?
When i was last in RotRA, in late December, I also noticed large numbers of small yellow ants in and on several of the herp enclosures.

@Swampy very likely they are

The beetle version of my favorite rhino!
