Hey guys, newbie here, Sexy shrimp has been hanging out on my Duncan for a couple of days and I noticed the coloration on the stem has been decreasing not sure why or maybe I’m overthinking it? Hopefully pictures aren’t too bad lmk if I need to remove him he loves to hang out on the frag rack. I target feed my coral enough to leave leftovers for him daily. Has he targeted my duncan? The green coloration has spots of off white on it and just wanted to play it safe as I plan to add more sexys. Parameters are trending within range except my nitrates we’re at 1.54 (Hanna) and phosphates are below .25ppm not exactly where as I’ve yet to acquire the Hanna phosphate checker but I’m using api. Duncan closed up after I had to shake the sexy off (not scared at all!) TIA
