how do I know if the my clowns are really bonded/paired?

[reefy]

Hi Folks,

so I have a black ice and a darwin clownfish in a BC29 for about 8 months, I bought it as "paired" according to the previous owner. currently only the blackice clown is hosting 2 rose tip anemone (got splitted rescently) he(i suppost because of a smaller size) wont let the darwin get close to neither of the anemone. I see the blackice shivers (showing surrender) when the darwin get closer to him. but he still wont allow darwin to get closer to the anemone. Darwin has to sleep by the powerhead. so my question is are they really paired? because I really want them to hang out together on anemone...

ps
only other fish i have in my BC29 is helfrich firefish (only comes out for food)
