Here's another of the anenome. I took the turbo out of the tank and scraped it off using a razor blade and a squeeze bulb of tank water. I reckon if it is tho, it may come back from my initial reading on them...?
The first pic looks like green coralline and the arrow pointing right looks like some type of mushroom coral. Hard to tell though since the pic is so dark. Pic 2 again, looks like green coralline algae. The anemone I agree doesn't look like an aptasia but could perhaps be majano anemone. Any chance of getting a pic from the top?
