I could use some advice please. One of my frogspawn has a branch that's turning dark and has lost its color. The rest of the animal looks great. My nitrates are around 8 ppm, ph at 8, no ammonia or nitrite. the rest of the corals in the tank look good. I give a dose of photo feast every 4 days. Should I just break that branch off or wait a few days. I noticed the color change start 2 days ago and it's going the wrong direction...darker and more translucent. Thanks for any advise you may lend.
