I was told this by Cherry Corals over feeding was bad, and I've heard it from other vendors as well. I wanna say Captive Reef and Cultivated Reef, but don't hold me to that it's been a while. Cherry Corals farms select acans and from the pieces I've seem come from their farm I value their advice.
Thank you for the compliment on my acans. They are the dominant coral in my tank.
I am not trying to start an online way because I don't know whether it is right or wrong, but I can see someone like cherry corals not providing the most accurate information to a hobbyist if they know they are growing them to sell to others.
I have heard both sides of the argument before, but no one seems to be able to prove one way or the other. I suppose it will continue as a mystery.
I don't feed my acans very often but they appear to grow pretty slowly. I used to feed them a lot and had some recession, but I think it was due to the lack of water changes and care due to work travel. I have noticed that in my new tank they have come back strong and I am not going to do anything differently than what I have been doing. currently, that means they get whatever they can catch and they might get some pellets every other week if I am in the mood to get my hands wet or already am doing something in the tank.
