sponge

Need some help on what this is on my gsp coral as it started on this one and is now on an other. A friend said it was a sponge but it didn’t come off with brushing with a soft toothbrush.‍ Is there a better way to get it off if it is a sponge the gsp is still opening fine

I really want get these sea sponge species. Need a manufacturer. Also need to know about the toxicity and how compatable it would be in a saltwater aquarium.

Hi just noticed I have a spong inside hammer skellington similar to the one I have on my rock in picture bellow…. Should I deal with it and how so?

Hey guys so I have this Galaxia frag, I’ve had it for months now and it’s been perfectly fine but today I noticed these weird sponge-like things around the frag, they don’t seem to be harming the guy and looking around I actually see some around the head of some torches, is this something I...

Howdy! As stated in the title, proud owner of a new Max Nano. Filled it with freshwater to check all of the systems. Pumps appear to be working fine so will drain and buy some RO/DI saltwater from the LFS and some live sand and rock to get started! A couple questions though: 1) What is the...

Anybody able to help me ID this or decide if it’s an issue? showed up about 3 weeks ago and has been growing rapidly over any surface ( rocks, macro algae, upwards) I haven’t touched it yet thank you

Does anyone know what this is growing on the torch body? It's hard to the touch so don't think it is a sponge. TIA

Found this on a live rock in my new FOWLR tank. Sponge? Type? Good guy or bad guy?

I’ve begun to notice 2 new organisms slowly appear on my live rock in areas of low light. tank is a little over a year old. Attached are 2 pictures the organism that is in the pic with one circle, I thought at first was a small feather duster but the frill ends do t seem to retract when...

So I bought a frag of plating sponge at an LFS and it came with some clove polyps and zoas. I especially like the clove polyps and would like them to survive but don't want them bothering the sponge either. Should I remove the other corals and put them in separate spots? If so, any...

So I noticed that my zoa garden is not growing as much, when I actually dust the rock off, I saw sponges limiting the zoa growths and actually the zoas are not growing where there’s sponges. What reef expert thinks? Asking for a friend.

Hello, what are these plating things growing in my Fiji live rock?

I found this thing below a section of my rockwork with 0 light, looks like a number of sponges?? Sorry for the photo quality, its a bit far back, so hard to get a good photo.

Picked up some live rock at lfs noticed this little guy on the rock. Can anyone help me identify what it is?

Hello! I was looking at my corals today and saw this guy on my candy cane. Tried looking online and I’m not sure if it’s a vermetid snail or a type of sponge. Can anyone offer any clarity and advise of what to do? I’m currently in the process of slowly transferring corals to a new tank and...

Hi Experts, noticed this grey 'sponge' like thingy on LR (about 1.5cm in size) and realized that it is moving (very slowly.. like a cm every 2 - 3 days) and it changes its shape (like stretching) when it is on the move... sorry for the pic quality. Is this a sponge and is it safe? Thanks.

Good afternoon, I am new to the hobby and have a 75-gallon tank with 2 clownfish, 2 gobies (added two days ago after quarantining), 6 coral frags, a skunk shrimp, a porcelain crab (that's been hiding a couple of weeks), and some snails. I noticed some things growing around the coral fragments...

I think they are but I am second guessing myself. small, white, anchored.

Hoping somebody can give me an ID on these two pictures. Thanks in advance!

I'm dosing a product to assist in sponge growth, which also requires some silicates. Will Phos 0,04 remove silicates? Does the resin have a higher affinity for silicates than for phosphates? Does it have a higher affinity for yellowing compounds, tannins than for PO4 and silicates? Thank you!

Hey all, I've got a growth growing between my two hammer heads and I'm not quite sure exactly what it is. It could potentially be a sponge, as the coral doesn't seem bothered by it at all. The heads stay open all day, I only found it at night doing a flashlight inspection on the reef. My...

i am looking for confirmation on type of sponge as well as what to do about them, I’m not worried as they are in my quarantine system, just curious as to eradicate or propagate lol, see attached below

Hello All, I have notice a few of these pink sponge type things popping up. 1) Are they sponges? 2) Are they good or bad? 3) Should they be removed? Thanks to all you experts!

Hey all- Been a lurker here for a while, but decided to create a build thread for my latest tank :D When I rebooted this tank my goal was to create a beautiful macroalgae display that would require minimal maintenance. Along the way, I started to notice that most of the things I planned on...

I had this orange stuff growing throughout my rock but now it's almost hairy in one spot. Any answers?
