I have a small group of green zoanthids that isn't doing to well. I had a high nitrate issue that I got undercontrol about a month ago. Everything has come around except this one group of about 20-25 polyps.The polyps are opened, but they don't have any of their lashes extended. My question is where is the best place to put it to try and get it back to normal. Alot of light or low light? what kind of flow?...etc. It's a 40 gallon breeder 120w led light.
