harmless filter feeders. natural part of a reef tank
So it has been at least 3 months since I added anything to the reef. Just maintenance. Any idea where this came from? What i am reading suggests they hitchhike easily?
i believe they form from the silicates in the RODI water? as any sponges do
A harmless sponge! At least that's what it looks like.
What is this?
I have been extremely ill for about a month so i haven't spent the time I would normally spend watching everything in the tank. I just noticed this today. The video shows little clear critters climbing all over. I tried to zoom in best i can without distorting the image. Should I be concerned?
Thank you! I am new to this and googling is beyond overwhelming so i appreciate knowing what it is and can finishing learning from there. Plus it helps to know what to search and read in these forums!
