Wellsophyllia Common names: lobed brain coral, open brain coral Difficulty Level: Wellso brains are generally very tolerant of most conditions, but stable alkalinity is important. Feeding: Wellsophyllia have a very strong prey capture ability. They may be fed any meaty foods including pellets. Lighting (Level 4 to 7): These corals prefer moderate lighting, but may be adapted to higher. Be sure to acclimate them when moving to higher light. Water flow: Moderate to stronger water flow is ideal. Placement: Wellso brains must be placed on the sand. They are aggressive corals with long sweeper tentacles, so be sure to leave ample space around them. General: Stable alkalinity is a must with these corals and calcium above 400 is best to promote growth.
