sponge

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?

I bought some zoas from my LFS four days ago and one of them had these little red dots on them that I noticed after dipping them. I dipped for 30 minutes and blew water on them every 5 minutes using a pipette to try to knock off anything but these were left, I figured it would be okay since I...

These white, spiky protrusions (to the bottom right of the cleaner shrimp) just appeared overnight in my tank. The closest thing I can identify it as might be a pink sponge, especially with sponge on the underside of the rock. Can anyone confirm? Otherwise, any clue what it could be? Thanks!

I've had this film/tubey structure encasing this rock for at least a year now, and I'm beginning to get curious of what it is. When I removed the rock from the water when transferring tanks in July, the film felt slimey but did not readily brush off. It seems to be inflated almost like a halo...

I've been doing some research on using cryptic zones in place of a skimmer and I'm curious how nutrient export actually happens. Obviously, with a skimmer we physically dump the waste down the drain. With a cryptic zone, sponges and other critters eat the dissolved organics, but nothing is...

So have a hammer and it’s always had some “dark spots” figured it was some discoloration of some sort. After tonight looks like it has spread ALOT since I’ve last paid attention to it. Might someone know what or why there is some blue Something growing around my hammer? Got the best pic I could...

Hi reefers I have a problem with spongeall over the rock whats the best way to remove it permanently ive had the sponge for ages keeps coming in no time at allĺ

What would you add/change? 3 month old 20g. The orange sponge has been receding since the beginning and there seems to be some bleaching so I’ve cut the light back from 14 hours a day to 10. Also the light gradually increases to 80 percent and then back to zero except the blue light is left...

Hey guys just wondering if this is Orange Coraline Algae? Or if it could be a Sponge of some sort?? Thanks!

Hi, I was wondering if fellow reefers can contribute to this question - What Sponge-in-a-Bottle can we buy to increase our sponge variety in a reef rank? I currently use Zeovit Sponge Power and the sponge life has really taken off in my tank. I would like to add to the variety of sponges in...

I can’t seem to figure out what it is? It’s multiplying into little blobs on my LR. Just want to make sure it’s reef safe.

Picture is of one of my mother colony’s. This sponge is very hardy and grows fast with no effort. Requires no feeding just light. It grows just like plating Monti. 3” - 4” frag for $50 shipped usps priority. I can do larger frags if requested as well. I can also overnight if requested price...

Anyone have an idea of what my feather duster worm is doing? The last picture is from a month ago and the middle was last week and the white one is this evening. Could this be normal? Is it just regrowing it’s chipped tube?

I found a nice piece of live rock with some copper banded coral on it. The guy at the store thought it was some rare sponge with an N name but he couldn't remember.
