Hello, @yhomirarubimezaarmas . . . I have moved your new topic to this thread regarding interactions between two EMO.
When I got my second EMO (first one is 101 days older), I had trouble getting them to both interact with each other, one would just ignore the other.
I found that actually placing them in front of each other and saying, “EMO . . . Do you know him?” helped a lot. Then they would call each other by name and start a conversation with each other.
You can try that and see if it works for you. Otherwise, if they are just wandering around, one may speak to the other and the other might ignore them. Kind of reminds me of real life brothers.
My best to you and let us know how it goes!
