“Grass” in my sand

[Charris]

I’ve never seen something like this randomly sprout out of my sand bed. Any thoughts? Just wrapped up my cycle and have introduced nothing in the tank except life rock and live sand.

Could be a siphon or worm fm sand? Interesting for sure?!

possibly initial growth of turtle weed (Chlorodesmis sp.) ... mature turtle weed looks very bushy.

... how's that rogue little sprout, @Charris? any more growth?

It grew at little taller and turned white. It was growing out of some crushed coral that was in the sand.
