Hi Have a massive amount of Aptasia in my display tank. Going to remove all the rocks and put new rocks in. I have everything prepped but I noticed these other things in the sump. The aptasia in the DT is all brown color, while this thing in the sump is translucent. What is this in the sump? It resembles aptasia but the coloring is different, and it also looks slightly different.
