Scorps can get relatively tall, not so much wide. D. pygmaea now that is a small plant...unfortunately mine seems to be getting swallowed up by a weird moss or maybe even a mold growing on the media surface.
No, but the more I look at it the more moldy is looks compared to any moss I have ever seen. Looks like time for some repotting...luckily it seems contained to the pygmaea pot but everything else is pretty full of various top dressings already.
Early action is the best action. Live Sphagnum has an anti-fungicidal agent in it. Unfortunately, most Sphagnum will drown out pygmy dews very quickly. Sphagnum compactum might help if this happens again.
