Anyone have long term success with an indo elegance coral?

Zero No3 is not a problem as long as it's being fed.
Some of them also like to have their hard part of the sckeleton being placed in the sand, you can try and see yours will appreciate it as well.

Not too much flow, just enough to bring the food and wash away waste.
Get cyclopeze and other similar food like oister eggs and it will be fine.
Or target feed paste mix of many different foods.

Nice coral!
