What can live with RETF?

However, that doesn't mean you can't get another tank .

I have seen many people try and intermix species of reptiles/amphibians together. Honestly, I have never seen red eyes do well mixed with anything except their own species. I have seen cases when they were mixed in with Dumpy Tree Frogs. But the dumpys get significantly bigger and risk having the smaller Red eyes get picked on.
I am sure some people have mixed and have had some success, but personally I have seen nothing but disaster occur when mixing species.

Edit: if you do I would be sure each animal is checked for parasites and quarantined.

The "Lighthouse" my frogs are living in now would be a good candidate for that. Or the Ten gallon vertical conversion I have too. Although they are both kind of small so I think my brother's old 29 gallon saltwater tank that has been empty for a decade needs to be repurposed.
