sponge

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.

I have a tiger cowrie (his name is Howard) and was wondering if he could eat a blue photosynthetic plating sponge. I read they eat sponges, but the plating sponges contain the hard glassy material ( forgot what it was called.) Could it work?

I've been wanting to dose silicates in my reef tank and read Randy Holme-Farley's article about silicate dosing. I know that it mentions you can buy water glass solution to dose silicates, but I was wondering if I could purchase this hydrous sodium silicate powder I found online to dissolve in...

I am looking for some sponges: Orange red Haliclona (picture below) Halichondria panicea or Neopetrosia exigua Grateful, if anyone can point to a supplier where I can buy any or all of the above. Thanks.

Got this as a hitchhiker on some live rock about a week or so ago. It was smooth, slimy, and uniform in color and texture when I put it in my tank. It hasn't moved at all, so I assumed it was some sort of sponge and would die off during my cycle. Three days ago it started growing what looks...

I can't remember when we got this, but I'm pretty sure we were told it's a small piece of blue leather coral. At the time, we didn't question it, but just for kicks, the other day I tried to get a better identification and well, could not find anything, but saw some sponges which look similar...

Hi all, This white mossy mass has slowly grown on my Duncan frag. Recently it has developed these cylindrical growths with little branches on it; there are a handful of those. In the attached picture I have circled the entire mass and am pointing to one of the growths. The closest ID I could...

Recently, this pink/purple foam thing started overgrowing zoas in my zoa garden. What is it? What eats it or removes it aside from manual removal? Here are photos of it on zoa frags I removed to clean. I'm thinking it is a sponge. I have been removing the impacted rocks and frags and...

Who’s currently aquaculturing a variety of: • Photosynthetic sponges • Photosynthetic gorgonians • Rarer inverts • Cleaner shrimp, etc.? I’d love to support them and give them kudos. It’s hard to find a reliable source of these that are 100% aquacultured.

I'm looking to seed a cryptic refugium with sponges. The goal would be to add a supplemental filtration zone. 1. Where should I buy them? I see some (old) references to reeffarmers.com, but not much else and google has not been too helpful. 2. Any specific recommendations on type of...

Hello! Heres my Chromodoris Annae feeding on a Random Black/Brown Sponge, If anyone could identify the Sponge it'd help a lot!

Just a list of items I'm trying to thin out the tanks. The more you buy the more you save. If your not sure what a item is pm me for a reference.

I'm trying to use one of my small 3'x 1'x 1' tanks for a quarantine tank. I got a sponge filter to just run in the tank, but the air pump is so loud, I am thinking of other options. Tank: I am actually using one just like this, that has an overflow box in the corner with a 1.5" bulkhead and...

I have 3 sponges that I got with my shipment of live rock back in June. They're still with me. Two are "ear" sponges and one is a yellow ball sponge. I've been feeding sponge power and supplementing with silicon. One of the ears looks like it might be losing tissue. Has anyone kept sponges...

I'm looking to make a quarantine tank out of one of my 36"x12"x12" acrylic tanks This one has a 1" drain with two 3/4"returns on top. I dont want to use a sump and the sponge filter with air pump I got is too loud. I was looking at canister filters where I could just run a sponge in the...

I have some pretty cool looking sponges popping up all over the place and Im wondering if they're truncates, and of course if it's anything I need to worry about. My guess is that they're a beneficial thing and a sign of a healthy reef, but I'd like your feedback. You can see in the second...

Literally have no pet store bear by and I'm trying to fill a gap in my overflow so an eel I have won't get into the sump. Can't find sponge filter material ANYWHERE in my local area and the closest shop to me is 2 hours away. Got a car sponge from Walmart. Rinsed the crap out of it in RODI water...

Sponge

Hi, I recently sprayed peroxide over a live rock to rid myself of some algae. It worked really well. Now, I see some bubble algae growing in on my clove polyp and blue sponge rock. So two questions: Will peroxide kill bubble algae? Will peroxide hurt the sponge? Thanks! Cheers, rant

HEY all, So I'm kind of new to the hobby... havnt even set up my first tank yet. Still working on getting all the parts for my 20G tank. I'll prolly have my first tank be a coral garden with a clownfish or 2. Anyways other than introducing myself I had a question. 2 years ago I bought a...

Hey guys, I've never seen this before so I have no idea what it could be and it's really hard to get a decent pic. I have a few yellow sponges on the back of some of my rock but nothing like this. It looks like the color of gel glue that we use to glue rocks, but it also has what looks like...

It's been growing bigger and bigger I guess it's some kind of sponge but can't find any information on this variety. Anyone seen this before ?
