@Pedoconfuego can link it if he wants toIs there a link to this thread? I'm curious to see what those corals look like.
Growth can always be altered by flow. Usually it guides the direction in which a coral will grow. I'm not ruling out flow as a factor, but those Tenuis have that distinct look I've began to notice more and more, and coincidentally in LED systems.
Not bashing on LEDs in the slightest. Just curious why that happens, and if there's a link between the lighting, params, flow, or what?
