Are my clownfish paired if they...

[Medici]

sleep together every night?

I bought two small premium snowflakes a couple weeks ago, one came a tiny bit bigger than the other. They've always kept close to each other, but also separate a lot during the day, but they sleep together in the same spot every night, sometimes so close it looks like they are touching each other.

Can I be sure they are already paired, or is it still questionable? I do not have an anemone for them yet, they just sleep in one top corner of the tank by a pump.

Thanks.

Here is interesting but long study on your question https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5066260/. It will take long than a week. Also when you see them do the simmer dance that is a sign they are mated. Good luck it sounds like they are on their way.
