sponge

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.

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...
