sponge

Is there a sponge that is reef safe? Meaning not competing with coral or becoming a nuisance for equipment and maintainence? Something that doesnt encrust and could either be used as a nice display piece or potentially in the sump with some live rock and miracle mud? Am I thinking too hard on...

these fleshy things have been growing on a piece of live rock that came from an lfs. The rock has only been in the tank a little over a week. They haven’t spread but appear to be getting bigger! What are they?

Anybody have any input on removing or reducing this yellow sponge? Surprisingly very little info on it on the internet. I read someone say that it can take the calcium and carbonate from rock and cause it dissolve. Well, I have it on my dragon soul torch colony stalks and one day one stalk...

Hello please help me identify this on my GSP coral. It doesn’t seem to bother my GSP too much as it still fully opens up during the day. But it’s white and semi transparent. Looks to be firm and doesn’t move with the current. Web like appearance.

Never seen one quite like it anyone can ID it came in on live rock rubble it moves , it has two small holes on each end - it is soft and squishy like a slug / snail / anemone and I have seen it squirt once or twice - looking to figure what it is if NPS or a pest or a fish eater Also anyone...

Hi all, I'm a new reefer and I have a new reef tank and its definitely in the ugly stage. I have about 4 of these weird whiteish growth on my rock work and don't really know what it is, a few people said it is some kind of sponge but I just want a second opinion on here. Can anyone help ID...

Barely had these ponies for a month and I am realizing I miss SPS too much. Getting rid of everything in the tank. Having a bit of a GHA issue. I got rid of my turbo snails because I really wanted to keep the blue hypnea algae. I’m pretty flexible with pricing. There are three of the bigger...

Any idea what these gray looking splotches are on my rock? The left-most one seemed to have moved from underneath another rock- possibly some kind of invert?

Curious as to what all these different critters growing on live rock in my NPS tank are? I know some are sponges but I’ve included pics of a few I’m not sure of. I’ve seen most of it here and there before but I feed my NPS tank consistently so I’ve noticed new growths popping up everywhere on my...

I've been getting this stuff in my Fluval Evo 13 back chambers for a while now. All three of them. This stuff kind of grosses me out because it looks like sunburned skin with hair follicle goose bumps :face-with-hand-over-mouth:. Lately it has been spreading into my display and is growing...

Curious if anyone has seen these sponges before. The large grayish white sponge is the same color as a pineapple sponge but much larger at 6” x 3” underside of rock. I acquired this rock from lfs. I saw what I thought was grey putty on the underside of rock and turned out to be this sponge. The...

My last post was removed from meet and greet??? I cant find it back? Anyways short version cuz im not typing my whole introduction about me and my tank again Is this yellow sponge?? Is it harmfull to the zoanthus coral growing on it?? (I assumed the zoanthus died like 3 years ago, only the...

Hello everyone, i noticed this stuff growing on the flesh of my Trachyphyllia. Is this a sponge? Because if you zoom in, it kinda looks stringy, like a ball of nematodes or something. Thank you all in advance

Hi all! For a little while now, my torch has had this clear white spongey stuff growing on its base and the past two days the torch hasn’t been out as much. 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...

I removed a good sized chunk of a chalice that had overgrown a rock with zoas. Once off I noticed this really weird sight. Looks like purple blob that has a deep hole in it and orange filament running through it and don’t know what it is ?!

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

Hi I could use some help. I’ve been working on my tank and noticed this orange sponge/growth on my frogspawn. Only on the skeleton and growing over the base wondering if anyone knows what it is and should I be worried?

Hii, I just found some really strange strings behind some rock work. It literally has the structure of spaghetti. My guess is that it is some kind of a sponge. Any guesses? Thanks!

I was wondering if the community had tips on controlling/removing a black sea sponge, It has not hurt my corals yet but my sea anemones seem to really not like it, I cut it back with tweezers/lower light, but the black sponge seems relentless. Any help is greatly appreciated

Hey guys, lately i battled against GHA pretty badly and got it over with, using fluconazole after a while. Now, Ive had this tank for well over a year, and of course as every tank, stuff that we’ve never seen before appears and it could be bad or good lol. Anyways I’ll be attaching photos of...

Hey guys & gals , happy weekend, hope everyone is doing ok Recently found this growing underneath one of my scolymia, appears to be some sort of sponge / truncate but wanted to post photos just to make sure it’s not something more invasive which warrants removal Here is a photo (attached) the...

This is the sump of my tank, it' about 8 months old. I put a little bit of rock from previous nano tank in here to bring pods in, etc. I was doing maintenance and noticed this stuff on the rock in the sump (it's behind my skimmer so I don't look back there much). I -think- it's a sponge? But...

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...

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...
