hitchhiker

I bought about 25lbs from gulf live rock and 4 of these anemones came on one of the pieces, can anyone help me I.d. Them? I cycled the rock for a week and all 4 survived.

Hey guys, I've noticed these white things growing on my Blasto frag when he closes up to eat. He's otherwise really healthy and appears to be growing. I wasn't sure if these were sweeper tentacles and a natural part of the Blasto? I'm about to upgrade my 30gal to an 80gal and want to make sure...

I apologize for the poor pic quality and the green algae, but I have no idea what little thing in the middle of the picture is. It moves like a starfish but doesn't have any arms. Maybe it is a star fish without arms?? I do have a couple of emerald crabs...

I found this baby starfish in my tank a few months ago, and didn’t see it for a while, so I assumed it was living in the rocks and coming out at night. He was on my glass today, and I just wanted to know if I could find out what kind of starfish he is. I’ll describe him as best as I can, because...

This lil guy appeared in my tank... not 1 of the ones I remember putting in. I believe it might have been born in the tank. I know I posted a picture before of what someone identified as snail eggs, but also mentioned they never hatch. Can this possibly be the result? Also what type of snail is...

Found this amazing little dude earlier, ive got a stomatella and this isnt him for sure. He isnt a lettuce as far as i know. Who may he be? Hes a very pleasant guest to have, hes caused no trouble and is quite the looker. Friendly and clean, i rate him a 10/10. Where can i get another? Bunch of...

I noticed a few of these popping out of my Scoly's base. Any idea what it is and if they are harmful?

Hey guys, just noticed this thing, and wondering what it is... Was thinking aptasia but not too familiar with it as I've been lucky enough to never have an outbreak. There's also a few pepermint so thought they would have found it if it were. Let me know what you think. Thanks!

Hey just wondering if someone can let me know if this is a vermetid snail. I’ve had the coral for a while. They were very prolific in another tank, but then they eventually all seemed to die off. I’m also wondering if this snail may be dead and it’s just a husk. Thanks!

Hello everybody, quick question I have a pretty large population of copepods in my 25 gallon Innovative Marine lagoon tank. But here is the kicker, I have a GSP that is swarmed with copepods, Its slowly opening up but i think it might be agitated by the pods. But heres the actual kicker in...

Currently drip acclimating my new coral order and noticed this on the base of my blasto. Thought it was aiptasia but not sure with the way it retreats back inside (see video). Any help is much appreciated.

Hey Folks, I’ve got a piece of rock sprouting something I can’t ID. It’s sprouting in multiple different places on the rock. LFS couldn’t help much (doesn’t help that my video isn’t of the best quality ). All I can tell is that these very small guys are growing in little groups of 4 or 5 heads...

This just showed up recently attached to the back wall of my QT tank. It is about the size of a dime. Any idea what this is? The arms move around a bit (front and side shots included).

Had some red algae pop up maybe a year after I bought a small piece of live rock. Have seen similar different species in ID threads but unsure. I think it's attractive and would like to keep it, just want to make sure it's not invasive or problematic in any other way. So far so good hasn't...

Looks like some sort of a pod but its huge? Roughly 5mm body and a couple more with the antlers. When its swimming about its straight like a stick and then when i hit it with some flow it curls up into a c-shaped ball. One of the good guys? Can I throw it into the fuge?

So last week I saw a few of these on my rocks, and then upon doing a water change, looked in the back chamber of my aio and saw A TON OF THEM, cleaned a lot of them up and scraped/siphoned out, but I looked again tonight and there’s more- hopefully not a big pest- any ideas?

Hi... I got this white speckle on a sick staghorn. What's that? Is it flat worm? Removal necessary, but how?

Hello! I’ve noticed this brown fuzzy looking thing popping in and out of a hole in my hammer coral skeleton (bottom left)I made sure to dip the coral before adding it to my tank, but I guess whatever it is, wasn’t phased by the dip. Any ideas what this could be? Is it harmless, harmful? Hammer...

Hey all, I just finished my weekly reef roid feeding and noticed my sand bed moving. Upon closer inspection I noticed all these tan little snails with their trunks up looking for any globs of food resting on the sand. I’m not too worried about any hitchhikers in my tank as I’ve already found a...

Hello! I bought some dry live rock and am in the process of fishless-cycling my tank. Today I just noticed this little guy and can’t quite seem to figure out what it is. A feather duster of some kind maybe? Hopefully nothing bad!! Thanks!

Saw this guy on my glass a bit ago, so I sucked him up with a small syringe and put him under my microscope. Sorry these arent the best photos, they were taken with my phone, I have a phone camera mount for my telescope but it doesnt work as well with the microscope, so I couldnt go any higher...

Hey everyone, I got a hitchhiker today. Not sure if he's reef safe or not? He's tiny at the moment. Any help would be greatly appreciated. Thanks

I just finished drip acclimating a huge RBTA. I dosed 2mL of Seachem Reef Dip in a bit over 750mL of water he was housed in. Once I did that, the little critter below jumped off of him and started going nuts - jumping in all directions like a flea. I included a photo of a Chinet plate with it in...

Hi All, We're in the process of moving all our corals from our nano to 100g (no live rock), while checking/cleaning our one of our corals it accidentally broke where the skeleton had died (we've been nursing it back to health) in doing so it revealed the frag plug below which low and behold had...

Hello everyone! This is my first time on a reefing forum. I made an account because I can’t find any information regarding what’s going on in my tank. 32 gallon LED Biocube All levels are completely fine and the tank is doing great other then the literal 2 - 300 slugs that seemed to develop...
