Last month, I took it out to dip it and I carefully used a knife to scrape this stuff off. It was crunchy and sponge like but I managed to...

    Green sponge identification!

    I need help identifying this new sponge? I haven’t added anything to the tank in ages it doesn’t seem to bother my corals or nem. About the sizes of a small worm, they don’t move and are firm when touched. They don’t fluoresce under actinics. Any ideas? Ignore the hair algae

    Hello, the following sponge is taking over my tank. It's literally growing over ALL my rocks and covering the base of some corals. I know it looks like cyano bacteria, but the thing underneath when trying to remove it manually is definitely a sponge like thing. I tried removing it with a...

    Interesting Filter feeder and Sponge ID help

    This post is just out of general curiosity. I’m assuming these are simply harmless filter feeders of sorts. For some perspective, tank is about 4yrs mature. The sponge is mostly growing in dark spots underneath live rock. The new rock I am curing has a newer growth on top as seen in pics. There...

    What’s on my sponge?

    I bought a sea sponge a few months ago. It was doing great for weeks, then fell over between some rocks for a few days. When I pulled it out of rocks, it has some white and brown goo on it.

    Pineapple sponge?

    Sorry for the bad pictures. It’s i. My fluval 13.5 and I didn’t scrape off the back side of it. You can kind of see it but they look like white webs all over the chamber in the back. Looks as if they’re keeping the chamber clean of detritus in the first one but the second chamber is a little...

    Propagating Orange Tree Sponge: can I simply cut and glue?!

    My orange tree sponge looks healthy: great color, upright, strong, healthy tissue. I do not like looking at the plug it came in on. The sponge would be more attractive encrusted to live rock. So, can I cut it and gel superglue it to an indent in the live rock? Also, if i leave an inch of the...
