I picked this up at my LFS. The guy said it was "like one of those [name] ones", and indicated a hand-sized chunk of monti. I'm not sure if they were exactly the same, as the big one didn't seem to have any green. He called the bigger one by a two-word name that included "madness" or "insanity", though I don't remember exactly what he called it. Anyone want to guess what a reddish, bumpy, encrusting monti called something like "[word] madness" would be?
Is this a monti setosa? A lot of the pictures of those online are all sorts of lumpy and branched, and none of the several bigger pieces had any sort of branches. They were bumpy and sort of ridged, but definitely not branched.
I have another encrusting monti, a Chili Pepper. If I put these two near each other, what are they likely to do at the point where they meet? Would they just do the usual encrusting SPS "try to grow over the other" thing, or would they sting and actually cause each other problems beyond the very edge? I think it would be neat to put the red-on-green coral next to the green-on-red one.
