sponge

Hi Guys I added 2 new live-rocks to my tank and a week later I started noticing sponges appearing. One White and One Yellowish. They grow flat like a mold with small pipe like tips. Seems like they prefer darker places, they star appearing from under my fragplugs. Would they be good or bad?

My photosynthetic red plating sponge has been growing great since I bought it at about the size of a silver dollar with only two little fold/plate. It is now about 6 inches across with multiple folds/plates/levels and still spreading out BUT the base is deteriorating. If it does not stop it...

Hello everyone, Please see Attachment for my sump design. Here are the key ideas of my sump: - No Filter Sock, use Sponge instead. (I find it easier to change sponge in this design) - But the Sponge filtering happens AFTER protein skimmer for 2 big reasons: Reason 1. Get must crap out of...

Just need an ID on this. I have had the tank up for a little over 2 years now. At first, I thought it was a sponge, but not so sure now. Thanks for any help provided.

I have been gone for two days and finally got back today. I come home and there is this brown spongy stuff all over my rocks. Any idea what it is?

I have a 72g reef that's been up and running for 4 years. I've recently found this odd velvet-like red sponge that started very small but has spread all over a number of my rock formations. I've scoured the forums trying to ID this "pest" but it seems to be frequently misclassified as cyano. It...

Hello again, I have had this stuff, usually white but sometimes black, growing on my LR that also has a layer of Green Star Polyps growing on it. The pictures I have attached are the pieces I cut off the live rock because of fairly rapid growth. It is very soft to the touch and it is only...

I noticed something growing around my zoas, Kind of forgot about it after i set my tank to having blue lights(couldn't see it). Here is it on the rock. And here is some of it after i scraped it off

Hello fellow reefers, trying to identify these white webby masses that are accumating on one side of my tank over the rocks. Ive narrowed it down to sponge or fungus? Any ideas? Chris

These things started growing like crazy all of a sudden, and dont know what they are. While taking these pics, i noticed that they look like little pineapple sponges, but not sure. There's so many of them! Theyre only a few mm long and popping up all over and im concerned about them. The last...

Hi All, Hope this is the right section to post this in... I have white stuff growing all over my live rock. Looks kinda like hair algae but it's white (kind of resembles roots spreading over the live rock). Some people are saying it might be a type of sponge but it grows more like algae...

Hi does anyone have ball sponges my lfs has some and they look pretty cool. I know sponges can be hard to keep but I have heard ball sponges are easier

So I had a small green star frag that died (cheap led lights). Whittled up to just a small skin left where it was glued. Since it died months ago a small patch of dark purple growth started. The purple growth hasn't spread past the dead coral frag. Then a small patch of translucent/white growth...

I got this frag at a LFS and was told it was from Australia I believe but without much other info I am not sure what I have. I am asking about the red "sponge" in the backround that is in focus. I did not have any better pictures at the time but figured that this one may be enough. I know it...

I think this is a sponge. Do I need to do anything about it?? Will it overgrow the polyp?? If you need info about its feel, it is depress-able and rubbery.

Hi. I have the orange sponge coral below for about four weeks now and seemed to be doing fine. About a week ago it started getting black tips and seems to be getting bigger. Does anyone know what this could be? Thanks,

Hey, hoping someone can tell me what the strange sponge like organism is that I have growing in my tank? I removed a piece of live rock, and the part of rock underneath had a strange sponge like substance with spiral patterns. In the last few weeks these spirals have risen and are now like mini...

Something I noticed about my live rock is that over time I realize how many sponges have appeared in and around the rocks. The most common I seen is a pale, white-colored one that normally just encrusts rock. It's very frail to any firm touch. Sometimes it branches out, normally deep inside...

Hi all! One more super quick and (hopefully) easy question. All I need is a simple yes or no answer, more is fine though! So i just ordered my media basket for my biocube 29. There is a sponge that the water goes through when it goes into chamber 3 (with the pump). Do i take out or leave this...
