are you guys sure you have the real one? (just checking b/c a couple impostors are coming into the trade)
i've never had issues with mine, its growing like a weed and always has been.
i havent seen any combo of flow/lighting make it upset so far.
only time i've seen it mad is when i fragged it, the frag looked very sluggish for a while until it started getting some polyp extension and it healed where i cut it.
i bought mine more than 2 years ago from hugo snipersps
do a search in the selling forum with my name and you will find when i bought it on RC
