These anemones were originally one Rose anem that split a week after I bought it. They are about 6 months old in a 90 gallon aquarium that is about a year and half old. I have metal hallides. I have tested the water quality and everything seems to be checking out fine. I've read that nitrates are bad for anems so I tested them and they are testing at 0. Is there anything I'm missing? These just don't look healthy to me. One of them is wondering around the tank and is now sitting on my GSP. What am I doing wrong?
