Candy cane tank placement

[Atmosphere]

So I'm new to the saltwater hobby but not new to tanks. I have to say saltwater is a whole new world then freshwater but so far it's been exciting.
Anyways I got a candy cane frag yesterday from my local aquarium store and just wondering if I read up correctly on these things and just wanted to get other peoples opinions on them. I have a 28 gallon jbj nano cube cf quad (I know just pc lighting). I put the frag mid level in the tank from what I read with pc lighting that would be the best spot just seeing what other people have done as far as placement. Also they guy told me they don't need to be spot feed but from what I read it doesn't hurt to spot feed these at all and what is every one using to spot feed these?

Your research seems good. Canes should be fine anywhere in your tank, but they'll take any light the PC's can give them. Mid to high will probably be great. They don't need food, but feeding them is fun, so go for it!

Under PC mid-high. I try to spot feed mine but they seem to not eat then, but rather on their own time...Probably at night!

I moved the candy cane down to the bottom it looks like its bleaching on one of the heads. And theres a damn tube worm living in the middle of the coral. Ive been feeding it with filter food to try and get it healthy and growing. Heres a pic tell me if its bleaching.
