I picked up a spider sponge from my LFS last week, from what I understand they are really hard to keep but I couldn't resist getting it because it was a smoking deal. I'm curious if anyone one here has any experience with this coral? If so what did you do to keep you spider sponge healthy? From what I understand they need low light, high flow, and should be feed phytoplankton regularly. On mine polyps seems to be extending quite well and overall the coral looks happy thus far but this morning I noticed a small portion of the tip of one of the branches has lost its color. Really not sure if there is anything I can do to fix this or prevent it going any further but any input or advice would be appreciated.
