Dwarf grass

[jmp3475]

I recently purchased Dwarf grass and it seems to be growing fine. New sprigs are starting to pop up throughout my tank which tells me its spreading roots as it should. My question is about little bulb like tips that are growing on top of the dwarf grass, on some single strands. It look like normal growth but some of those bulbs are dark in color. Should I be concerned?

Your dwarf hairgrass is likely Eleoacharis, which flowers at its tips. This is very likely what you are seeing.
