pest id

Hello I’ve been wanting a dwarf seahorse tank for about a year now but I’ve been having trouble with pests, specifically these small jellyfish and anemones, even taking down my last tank and starting over again because of them though I’ve already delt with the anemones, the jellyfish occupation...

Hi everyone, I bought this Acan about 2 weeks ago. It doesn’t look so great and it hasn’t been improving. It appears to be receding and just seems generally unhappy. Last night, before lights out, I noticed this weird thing on the edge of it and I watched it for a few minutes. I didn’t see it...

These keep coming up on my rock. I am not sure what they are and if they are harmful to my coral? Any help would be appreciated.

What is this on my frog spawn ? Should I remove it? Or dip it?

So, a friend of mine found some free live rock, with clownfish and corals from someone that was shutting down a small tank and asked me to put the fish in my QT since it was empty while he finished setting up his QT and DT. Long story short, the previous owner had a bristle worm infestation...

A couple days ago I didn’t see any of these. Now, they are everywhere. What are they? Thanks for the help! Picture attached.

Does anyone know what this fleshy-looking spiral thing is, at the base of the duncan? Sorry for the blues/poor quality. I can try to get a better picture tomorrow, if it helps. I had thought it was a new head growing - it's been there since I bought the frag two and a half months ago. It's...

I have a lot of white specs appear on my glass. They are pure white and move very slowly if at all. I managed to get a sample under the microscope. I have a few trochus snails in the tank which have been releasing eggs lately after a water change. Can anyone help ID them from the pics attached...

Hi everyone, this is my first post, I hope that's ok, and hope I'm doing this correctly. After neglecting my tank for a while due to pregnancy and having a newborn, I am slowly trying to get it back on track. I noticed this sponge-like growth in a dimmer part of my tank, kind of under and...

I put my acans on a new rock together and now I found these white tubes on the skeleton. Any help in ID would be much appreciated.

These snails are everywhere in my tank in all kinds of sizes and appear to only be active at night. Are they coral pests or beneficial hitch hikers?

Hi all, In relation to ticked off corals from time to time, coupled with being able to sleep late and wake up late (vacation for the holidays), I’ve been looking at my tank more at night, i.e. during total darkness. I noticed quite a large population of these, and they seem to be congregating...

Hi first time reefer I’ve had my tank set up for 6 months now and I’m wondering what this is. Should I just leave it alone or remove it I’m thinking spaghetti worm but not sure

Found this on my hammer is it good or bad? Thanks

Looks like tiny tubes that each have two tendril things. I think they could be Vermitid snails but none of the pictures online looked quite like them. Another guess is Hydroids but that seems very unlikely. They have only popped up in this certain area next to my Mushroom.

Hi Notice this a week ago but thought it was coral slime at first…… Double check it to day as I though it was weird been in same place again….. As soon as you shine a light on it it retracts into the rock work….. either think some type of brittle star or worm …. Video is crap as just off iPhone...

Can someone please identify those small moving black dots on my Scolymia button coral? If my calculation is right, the dots are very small, ranging between 0.04 and 0.06 mm. Which should be 10 times smaller than the Black Bugs, if I'm right. For scale reference, the head has 1 inch diameter...

I left my house for 2 days and came back to my tank with these guys in here. Anyone know what these are? The video isn’t very clear but they look like baby shrimps. If this helps, I turned off the lights during those two days to try and get rid of some of my algae and see how they would respond...

Hello everyone, I hope this message finds you well. Attached is an image (as close up as I could get of a new arthropod in my system. I believe it is an unwanted sea spider. I have only noticed them on glass and back panel of my AIO system. There are a few dozen at this point and i only...

Wassup Reefers, found this tiny orange legged crab hosting in my elegance coral today. Anyone have any idea what it is or if it’s bad for the corals health?? Thanks in advance!

Hey y’all, I need some help. I’ve got a more detailed background of my tank on my build thread, I’m going to post a few pics and if anyone can help me ID I would be so thankful. I’m going to have to restart my tank & rip clean, especially with all these issues, but I would still like to know...

Is this a “strawberry” anemone? I guess that’s a mojano? That’s what people in my area call them. Should I murder it or is it reef safe?

美女と野獣ゾアを繁殖させたい。 しかし、彼はまだ健康に見える成長していません 私が彼の断片をチェックすると、彼の組織は革のようなもので覆われていて、彼の組織は旗から剥がれていました。 どういうわけか原因がわかります ・藻類は旗で覆われています ・接着剤を大量に使用しました ・ストリームが足りない 私はそれらを解決しました。以前より頻繁に水を交換しました。藻を取り除きました。 静かに見るべきですか？ そして彼のカバーは彼自身を保護していますか？

Hello, ive has this acans for a while now and its been doing pretty well, but when i woke up this morning i noticed what looked like feathers coming from underneath it, i picked it up and it had a long white tube connecting it to the base. Im wondering if anyone know what this might be, id its...
