I think it could be that they don't multiply very quickly (i.e. create a new head). Mine has just become bigger over time. I treat and feed it like a sea anemone and have had no problems. They add some nice colour to the tank and their sticky tentacles will also catch any food particles that pass by during feeding. I start by shutting down the power heads and filter and target feed it (as well as the acans) but it will continue to catch particles after I turn everything back on. Overall, I don't think feeding is that big an issue.
