GBTA split ...

sometimes the anemone turns very little especially with luner lights and then the anemone strech again

I don't think its splitting because when anemones split, they split down the middle so each side has a half of a mouth. Your GBTA seems to just have a weird form that slightly appears as it is going to split.

You know why is stretching like that?
