IMO, that is not a lobo, if it were, it would form individual heads. Symphyllia on the other hand will stay ''open'' like the one you have. Keep it lower in the tank or on the sand with low-mid flow
The distinguishing characteristic between Lobophyllia and Symphyllia all comes down to skeleton structure. The corallites on a Lobophyllia have separate walls, whereas a Symphyllia's corallites have shared walls.
