coral pests

These small white hairs have appeared on one of my zoa frags and I can’t seem to correctly identify what they are. Can someone tell me what these white hairs are? I was also wondering what type of dip i should use to remove these hairs? Thanks!

Hi, I’ve tried to search for this type of pest I pulled off my elegance coral, but I’m new to the forum so I may have overlooked a relevant thread. I pulled this crab/tick like creature off of the flesh of my elegance coral. The coral has been looking a little off for a few days, I thought it...

Hi All, I’m having big issues with my Trachy all of a sudden. I’ve had this coral for about 4 months now and up until about a month ago it has always been blown up and inflated and happy. I first noticed what I thought were eggs, fluorescent mucous like deposits. (Found out this was just the...

I’m pretty new to the hobby and this is my first post on here, so hey all! I’ve noticed at night and in the mornings when the lights come on that I have small bugs that come out and crawl all over the sand bed. They disturb my corals pretty bad at night….my corals all get pretty irritated, and...

What coral dip do you use? Are you loyal to a certain brand? Use depending on situation? Don't use it at all? Let me know down below.

I can identify some pineapple sponges. What are those white hairy things? Are those hydroids?

My small piece of the ocean, 12 gal JBJ nanocube, has been running since June. We have soft and LPS corals, crabs, and amphipods- oh my. Everything was going well until the Zoas snapped closed and lo and behold- the dreaded Zoa Spiders. Sucked one out and dipped in iodine immediately, but I am...

Hey everybody, I have something that seems to be eating only my lps corals. I can’t see what it is but it leave a white stringy residue as it’s eating it. I have dipped the corals and seems to help if I catch it in time but will show up on another frag soon after. But on every one it leaves a...

I’ve been very overwhelmed with setting up a coral qt and I got to thinking— maybe the possibility of pests isn’t such a bad thing? Having the perfect “pest-free” tank with 100% assurance feels a bit....sterile. In a sick way, I kind of enjoy the slight possibility. Pest prevention practices...

hi y’all, quick question.. in the attached video there’s a coral that’s clearly not happy and on its way out, but there’s a weird ‘wing’ looking thing coming out of it, literally reminds us of ‘fly wings’.. could this be a type of pest and if so, are our other corals at risk? any ideas and...

Hi all! I got a couple of frags and dipped them. So what came off? Two asterina stars, a bristle worm baby and a couple of red flatworms ( I think). I dipped them in Coral RX. My tank is pretty new (7 months). And although I know there are people who don’t mind bristle worms and asterinas, I...

Hello! My name is Tyler and I’m new to the reef aquarium hobby. I’ve got a Fluval Evo lll 13.5 gallon aquarium that has been running for a couple months now. I purchased a zoa frag from my LFS to monitor for a while in hopes of it doing well to see if I was ok to start to add in a couple...

Hello fellow reefers. I just noticed these small white creatures in my quarantine tank. Attaching some pics and vid. Please let me know if I should let them be or removey corals n dip them. Vimeo link

Anyone can ID this for me? Today one of my hammers died. Last night it wasnt happy and looked extremely stressed. Sucked to see it that way cause it was fine just hours before in the morning. So i dipped it in iodine and put it back thinking its a bacterial infection. At midnight i came down and...

Hi All, I received 4 acro colonies last week and I've had to frag 3 colonies down into smaller sizes due to STN and acro burrowing worms (not red flatworms). These top two photos show the eventual die off of the skin and where tentacles from the worms extend to feed (neither of these...

I began my first dipping procedure for the Indonesian Acropora I received last week and I found this guy in the coral branches (he is not a good acro crab).

Hi Reefers. I’m after some help as I’m really unsure as to what I’m dealing with here I noticed one of my Acro’s is struggling and spent some time studying it. After a while, I noticed some very small black dots that moved ever so slowly. Only a couple but I’ve seen them on the stick now for...

Hey everyone. I am Vann. I really tried to do it right with no live rock and going slow, but I am pretty sure I got some blue hippo tangs with ich and what a ride since then. Being new I didn't know what ich was and in trying to figure it out I have lost more than I want to admit to. Now...
