So this is a weird event...
The Cardinal I put in kept starting at the rock above the clown fish and his treasured bubble coral in the evenings. Looked like Darth Vadar doing a mind trick. 1 week on and now the Clown, Royal Grammma & Chromis are all doing the same all day long. It's been about 2 days since the clown left the bubble coral and as each day goes on, the bubble seems to be opening up less and less and completely recedes it's bubbles sometimes. Not sure what to do. Will give it dip in revive and see if that helps.
