So my tank has been up for about a year now. I am adding coral slowly, but I'm baffled by the growth. Is started simple with a few mushrooms and a leather. After a moth of them doing well I added some Acans and Candycanes. Now my red mushrooms are shriveling, my leather hasn't opened in months (I just moved to higher flow and he opened yesterday), but my LPs is thriving . I bought each Acan with 4 heads... Each one has 12 new heads in the past month... Each Candycane I bought with 2 heads, but they each have 4 new heads. Since my softies are so hard to kill why are my LPS doing so much better?
