yes SM , I know its a difficult coral and needs frequent feeding. a friend gave it to me , hard to resist the coral it adds colour to to the tank and with the scrubber running I don't have to worry so much,
the scrubber algae stop growing for awhile , till I fed the tank more, more food for the fish and more coralfood due to the red chilli tree and the scrubber came back to life.
hope it goes well , bytheway the Linkia is doing well too .
