I thought it might be, but that’s the best photo I can get from iPhone at 5x. So harmless?

Sponge is generally a good thing sign of a healthy tank

Thank you, I’ll look into it. Do you know if they are healthy for the system or invasive?

I thought dictyota was a blue green color.

i think under uv you’ll see the new growth with that blue but it’s just bland brown green.

I had it in my tank and it was blue green under halides.
