So I just added these two colonies of Zoos to my 15G column about 5 days ago. Colony on the left seems happy and opened up right away. They're actually a little more closed than usual cuz the light just came on not long ago. The colony on the plug to the right of them however has not opened yet... at all. Seems like they're stretching to get more light but that surprises me as they're at mid to upper level in the tank and I have an AI Prime 16HD over them running the Ecotech Marine AB+ spectrum. Maybe they're a higher light demand zoo? What do you guys think? Should I raise them up higher?
