Got frags of a monti cap and a monti dig about two weeks ago and haven't noticed any growth. So how do I tell if they are happy? The monti dig has it's polyps extended all the time, but has two white tips (had them since I got them). Are the tips necrosis or is it an area of active growth? The monti cap has some polyps extended, more on it's bottom side than it's top side. The tips of it have remained white as well. The frags or just under the surface under VHO lamps and get med to high flow.
