Mushroom?

[Saaqib_Ansari]

Hi was looking at my tank for a fish that’s been missing and I’ve found this bright green thing at the back of the tank is it a mushroom?

Yeah, looks like a discosoma mushroom.

Yeah, looks like a discosoma mushroom.

Where on earth did it come from ? I did lose one a few months ago

I second it being a discosoma. discosomas multiply very fast in stable parameters. I have one in my system and have at least 5 penny sized babies in the rock work. That one probably decided to detach! Nice find!
