I have had this anemone for around 7 months and it has split about a month and half ago and since then the mouth has been open. Any reasons why this is happening?
I have a seen nems push their inside out of their mouth and stay like that for a month or more and then go back to looking completely normal. Nems seem to really have a mind of their own (small though it may be!).
My RBTA's mouth is closed and normal, while my LTA's mouth is open a little and has been for a few days.
Nems are weird critters.. I think that's why I like them so much, they know what they are doing but we can just speculate what's going on.
