hitchhiker

Anybody able to id this bivalve?

Need ID please He was in the coral base that I was dipping into Coral RX, promptly died after but was wondering what type of snail it was. Sorry for the picture quality it was hard to get a good picture. It had a red shell with spots. Reminded me of a lady bug

Long white stringy creature living in chaeto. It retracts when I touch the water or it senses vibrations on aquaclear filter. Maybe some kind of worm??

Hello everyone, I am having trouble with getting a positive identification on what appears to be an Isopod of some sort. This is the second time they have appeared in the water column since I have upgraded aquarium sizes and added live sand. They resemble Cirolanid Isopods, but they are very...

Hello guys Got a new creature on my live rock that seems to be a filter feeder... not sure where it came from or if it's bad... any help is appreciated! Thanks

So my tank has been cycling for about a month or so now. Live rock, and live sand. All my tests are looking good. I think I'm about finished. I have my heater out because I'm still stirring sand dust out (I was silly and didn't rinse) but my water stays around 74 even without. Tonight I was...

Is this a (the?) culprit for my unhappy zoas? Pics not great, but 2 large antenna and visible eye spots. Could also be a slug -- the purple portion is almost firm like a mantle. As always, burn it, sump it or good guy?

I found this in my filter sock tonight. Its about 3/8-1/2" in length and very active. It curls its back tail up under itself and seems to have front arms/legs held tightly to its body like a pistol shrimp or mantis shrimp. Kind of swims on its side... or maybe that's because I don't have...

Any ideas what this thing is? Its been moving slowly for the past few weeks, started out along the base of the coral and I missed it - its currently on a mushroom finger leather coral... Survived a coral dip... Is it harmful? what do I do with it?

Does anybody know what type of coral this is? It came on a rock that was given to me by a friend (some zoos are on the rock as and a couple palys recently started growing on there as well). The rock was thoroughly dipped so I doubt it is a pest of any sort. Apologies if the photos are bad :-( I...

Update: Upon further research, I was able to educate myself a little. It appears the snails are harmless and the limpets?; are as well. The flatworms though; not so sure. Hello all! Found a few new critters I haven’t noticed before. Seen a few of these little snails climbing around. They’re...

I just found this section and thought my latest video would be perfect here...;Walkingdead

It looks like a nassarius without a shell. However, since I have never actually seen a shelless nassarius, I have no idea. Please tell me if the little guy is a friend or foe. His life is in your hands. Thanks, Jim

I found a weird branch coming off an astrea snail today. A picture is worth a thousand words so here's a few.

After feeding my tank last night, I noticed some motion and took a closer look. It was a long transparent tentacle coming from the live rock. The head was wriggling around pretty good. I took video with my phone, I apologize for poor quality. Make sure to view in 1080p: I've gotten pretty...

Can somebody tell me whatthese are growing on my rock and if they are safe? The first one looks like a milky cobweb that easily comes off when touched. Rhe sexond one looks like a dandelion or an antena with a ball at the end. And is this yellow stuff algae?

Can someone tell me what these are? I know the one is a starfish but what kind?

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...

hi everyone, Noticed these brown spots on top of a couple trochus snails. Thought it was just brown algae so i scrubbed it a bit but it was still there. then i dipped some hydro peroxide on a paper towel to wipe and drench those spots--it just receded into crevice or pockmarks on snail shell...

This is the aiptasia that came in my live rock order from GLR about 6 weeks ago. Fast forward to 6/1/2017: He's in a 20g with no corals, only a valentini puffer, giant emerald, hermits, and astrea snails. Hasn't spread at all in 6 weeks. (Seems to contradict what a lot of people say about...

I purchased a coralline cluster and it arrived with what looked like a stomatella snail hitchhiker on the side of the bag. When I grabbed it, it rolled up into a ball like you see in the picture. What are we looking at here?

So I ordered a maricultured metallic green torch coral from LiveAquaria and it came with its very own sizable crab. It has hairy legs and green body and claws. I'm thinking it's an emerald mithrax crab, but I want to be sure before I set it loose in the tank. Can anyone confirm it's an emerald...

Hello. So. My tank has been established for a little over 3 months now and for the last week I've noticed this dang worm thingy. I can't see it when the lights are off, but once the day time lights come on I notice something moves quickly then hides. After a while I see it peek it's "head" out...

I just found this coral on some Florida aquacultured rock: This was about the best quality I could get with my cell phone camera. If anyone needs a better shot I'll see if my DSLR can render it better. Skeleton appears brownish/orange and polyps are green and fluoresce under actinic. The...
