I've had this purple monti some months now and its been growing like a beast. This is only half of the monti as i have fragged it into two. The issue is its polyps. The monti itself is a beautiful deep purple yet the polyps are an ugly brown. Over the course that i've had it its polyps have been extending more and more, now so much that i cannot even see the purple underneath. Just this brown. At the bottom you can see some of the purple sticking out. Whats the reason for the polyps going nuts like this? In the tanks where i've seen purple montis its never like this. Is it not getting enough light that its trying to filter feed or something? Surely 150W MHs are enough for them?
