What is this?

It's growing in my sump. I have a small slug and a few hermits but they won't touch it.

Hrm, im a newbie here but I think I just saw this on a video from mr. Saltwater tank. He talks about his fuge and the 2 types of algae that most people use. The first being chaeto, and that looks like the second one that several people dont like because it can go sexual and spread all over the tank. Again, noob here, just been watching tons of videos over the last month.


Caulerpa? sorry of that is spelled wrong.

Hi Javi
A better picture would be great if you can get one. Maybe turn the system off so there isn't any water turbulence and also pull a sample out to photograph? With a better picture someone here will definitely be able to tell you what it is.

Looks to be bubble algae. It's a nuisance algae that spreads quickly and is unsightly if it makes it to the display. Remove the rock its attached to and scrub it off or dry out the rock.
