Hello everyone. So I have a few different types of corals in my tank. Two types of gorgonians, a montipora, an orange leptoseris, two kinds of zoanthid, and lastly a small frag of GSP. Oh and also a Kenyan tree coral. So for the gorgonians, Zola, and tree are all very well and happy. The montipora is really midday about popping out it’s polyps, and the lepto is always great and vibrant. However, the coral that is not doing well at all is supposed to be the easiest one to grow. So much so that it is called a invasive coral. I’ve placed it on its own rock right across the tank facing the power head. But if barely comes out. I want to get some more to possibly replace it if it is too far gone. But how am I not getting this of all corals to thrive? You can see where it is supposed to be from my hand pointing to it.
