She pick that spot like 3 days ago and stay there. She got to strech a lot to find the light and she looks like that since she move there. I want to know if she's looking good?
Yes, that looks fine. If the anemone chose that spot and is staying there, it's likely happy. BTAs love to stretch out toward the light, that's not unusual at all.
looks beautiful and healthy
it's their behavior to stretch out and say hello to the light
bubble tip anemones worst behavior is that they move so much its sometimes can hurt corals by moving but at all it beautiful
