Greetings - first post . I just started a 28g 186 watt HQI JBJ nano tank and transferred my corals from their previous home for the past 4 months- a 14 g biocube with 76 watt CFB lighting. The corals have been in the new tank for about a month. Tank cycled for 6 weeks before adding them. Temp 78, SG 1.025, nitrates 0, calcium 400, pH 8.3, add strontium supplement every 4 days, change 15 %- 20 % water every week. All my corals look good but my neon green sinularia is misbehaving. At first it appeared to love the switch to the new tank, extending out for several weeks like it never did before. However for the past week it has shrunken up not extending its polyps from either two stalks. Its color still looks great but instead of looking like a cactus it looks like a tiny " hulk fist". To make matters worse when I was rearranging some landscaping tonight a piece of live rock fell on it

. In the middle of the bigger stalk there is a 1.5 cm linear streak of grey where the green was scrapped off by the rock. I have heard that finger corals will hunker down for a while but I figured a week plus without extending its polyps was cause for concern. I have tried placing it in different areas of the tank, more current , less current, more light, less light without much change. On one hand it isnt disintergrating and its colors are still vibrant,on the other its still closed up. ? delayed acclimation to new tank? Any thoughts or input is appreciated.
