So I got this zoa colony about two weeks ago there radio dragon eyes and something red. It was a killer deal $10! But after a couple weeks less and less open up. And it appears like there actually melting away. I can't find any pests at all day or night with a flashlight. Am, nitrite, nitrates are all 0. Salinity a steady 1.026. Temp is 79. There in the bottom of my 10 gallon with a 18 watt led so it's not a ton of light. Anyone have any ideas?
