Lobophyllia are very large polyped stony corals, and do well down low in the tank. Lobos take their time growing, but fill a nice area in any reef. They can eat meaty foods, and can also consume pellet food if that isn't snatched away due to their exceedingly slow response time. Shrimp and fish may grab the food before the coral has time to ingest it.
