I have a goni and it pretty much in the corner of the tank and has very little flow. Just enough to gently move the polyps. I would try some cyclopees. Also be careful not to blast it with food. You dont want to get a defense reaction verses a feeding reaction. If it reacts defensively, it wont eat. Ive had mine for about 2 months and am having pretty good luck. It hasn't grown, but on the other hand, it hasn't died.
