Neon Green trumpet Coral

[Beano1169]

Hey all I have had a neon green trumpet in my tank for 2-3 weeks now, it seemed to be doing alright but lately I have been reading that it my be sickly. The feeders arent out very often, and its not super puffed up. Im just kinda concerned because I do love the look of this coral. It has about 6-7 heads on it and they just seem skinny to me, I have been feeding phyto often every 2-3 days for my feather duster, should I increased it?
