hello! i recently added a purple finger leather to my tank. it has been flopped over for most of the time, which i thought was bad placement in my tank and so moved it to a higher flow. at the lfs i noticed that it wasn't open there. it has not yet opened for me and its been about a week. it appears to stand up when the lights are going off, and mostly at night. it has just recently shed a few days ago but continues to flop to the side during the day and stand sometimes at night. i read that finger leathers need med to high water flow and med to high light. water parameters are fine, so i'm not sure what the problem is.
