hitchhicker

Is this something I should be concerned about, or can I place it in my tank? There are red spikes on my trochus snail. I pulled on them and they did not come off (same with a toothbrush). It's a captive-bred snail from @AlgaeBarn

I saw this while looking at my tank at night while my lights were off, is it aptasia? Sorry for the bad picture

Hellos guys, just found this guys in my tanks. I was looking around the tanks at night, with all the pumps off and found this guys. I believe him to be a nasarrius snail, but it is striped. I could see his “antena” and had sobre stripes. Is it possible to ID a snail just by its shell? thanks

I bought a mushroom frag today which actually grew on a snail shell. I was debating on dipping it when I big Orange work came slithering out for the shell! Is this something I should try to get rid of with the dip or introduce to my tank? I currently don’t have any in my tank It actually looks...

There is a dozen or so of what seems to be flatworms on my favia. There don't seem to bother the coral at all. In opposite, it looks very healthy. And considering the number of them, it is not a recent development. I am not sure where they came from. What should I do about them? Dip the coral...

I bought my first ever coral about 4 months ago, a small 2 head Torch and a fungia plate coral, I dipped them both and got a small flatworm off the torch luckily. A few days into owning the torch and watching it get used to the water and extend, I noticed a little section of bristly exoskeleton...

Hey all, Can anyone help identify what this white stringy stuff is that I have growing on the base of my Zoa's? It took over 2 small polyps already. TIA

Does anyone have experience with Rapa Rapa snails and Sarcophyton? I have a toadstool coral that I added to my tank back in the middle of March. I purchased it from a LFS I was unfamiliar with so I did dip it prior to adding it to my tank with Seachem Reef Dip. It went through a fairly rapid...

I have just caught this one in the picture. It is in a drop of water so quite small maybe 5mm. One side looks like feather of some sort so could be a baby feature duster in loose

Hey guys I’m new to the saltwater scene and have had this 20 gallon tank for about 4 months so I’m not sure as to what hitchhikers are good and bad but I just seen this guy today and wanted to know on what to do with it.

LPS a ting funny last few days, pulled sample off an elegance, 400x showed this guy. Doesnt resemble a pod? What am I looking at?

Hello all .. so today bought a new wellsophyllia and i dip it in coral Rx pro .. nonetheless, after i add it it the tank i noticed its moving so i flip it .. and found this guy .. is there an ID .. good or bad? Looks like a snail. Please refer to the video

Found one of these on a rock I got from LFS. Didn’t think much of it, now after 4 months there’s 2. They’re about the size of a small zoa polyp. ID?

I've had my tank setup for almost 8 months now. Live rock came from Tampa Bay Saltwater back in September 2020. These guys have been around for a while and at first we were happy to have some anemones, but the more research I do I start to think they are Aiptasia... but really large ones! I...

Hi Guys, I bought a new hammer coral about two weeks ago and today I noticed a possible hitchhiker on the back. I dipped the coral in Coral RX Pro and Seachem Reef Dip when I got them. It seems to protrude and then goes back in if one of my hermits passes near. I’ve tried to take some pictures...

I I have two clam like hitchhikers on one of my snails. I thought it was a piece of super glue at 1st. But today I noticed them opening and closing when a fish got close to the snail. And they have balck lines on them. you csn see them in the pictures. What is it and is it dangerous?

So I know I have other issues I'm dealing with but I looked in the tank and seen this! I have no idea what it is or what I should do about it. Please help.

We ordered some Florida Cerith Snails and one arrived with something attached to its shell. I don’t think it’s aptasia because it doesn’t retract when you touch it or remove it from the water. It’s actually a bit stiff, maintaining its shape out of water. Apologies, my pictures aren’t the...

What is growing out of my snails shell?

Hi all, my first post here so bear with me. relatively recently have had a 37 gallon going for about 2 months. I started with some great live rock but discovered what I think is a bristle worm. wondering if i should let him stay or remove immediately. He comes out during feeding time between...

Just noticed this on a frag that's been in the tank for about a month. I haven't seen them anywhere else in the tank so I guess it came on the frag, but just now noticing it. Can anyone help ID what this is on the base of this hammer?

Hi guys, I have this super weird worm ive finally managed to catch. Its white and seems to swim really fast by wiggling quickly. Its superweird and havent seen anything like it Getting a good photo is hard since its never still. Anyone have an idea what this could be??

Hi! I just discovered this nasty looking pest in my sand and come to realize that they were living on my live rock. I immediately took of the rock and got as many as I can out of the substrate. I have fairly new dry rock so I dint think there living there but I did check anyways and there seems...
