Interesting observation. Apparently chaetomorpha doesn’t need much, if any, light to survive. The lights in this sump (Pirate’s Reef) went dark on August 28th. I just turned the sump light on for the first time on October 16th and the ball of chaeto is still dark green. 45 days with only a little ambient light from a window across the room. Strange.

crazy.
I only had maybe 3 strands of it in my fuge when I first put it in.
Now it’s out competing the sea lettuce :/
Chaeto is a beast
