We recently added a Pink Rose Bubbletip Anemone into our tank on Sunday. This anemone stays at a good size throughout the day but usually around 5/6PM it shrinks. I know corals/anemones do shrink when it gets darker in the tank but this size is crazy to me. Is this normal? The piece still has not bubbled, only looks like a long arm tentacles as well. Any tips/help would be greatly appreciated.
