Holy grail torch shrinking...help!

[miserkris]

I've had this torch that's a Holy Grail variety for six months. It was doing fine but for the past one month it's shrunk in half size.

I tried moving it to a low-flow low light area where it is currently please see the picture(right one). What can I do to revive this should I bring it to more light more Flow? I'm even feeding it frozen food once a week and I feed the whole DT too.

Other euphylia, torch hammer are doing well.

Thx

Check your nitrates and phosphates asap, dip it in coral rx and don't feed it
