  1. Hello everybody. I have been strolling around a couple of hundreds of forum posts, youtube videos or scientific papers and wanted to talk about one, if not the worst pest you can have in your reef tank. The vermetid snail. I have my experience with aiptasia, flatworms, coral eating asterina starfish and bristle worms, sea spiders eating zoas etc., but not a single animal comes close to the vermetid snail. The biggest difference between these kind of pests and others is that vermetid snails have no known predator. There are rumours that bumblebee snails eat them, melanurus wrasses pick at them (which is not true no single wrasse eats them as their hardy shell protects them from outside force), emerald crabs should eat them (which has never been proven). Some scientific papers say that Muricid snail eat them, but keep in mind that muricid snails are predators that hunt big molluscs and other parts of your cleanup crew. Bumblebee snails are too small to hurt bigger snails, but their reliability as vermetid eaters is questionable. What makes them so horrible: - Vermetid snails grow in every part of your tank. Your rocks, between your corals, inside your sump, on your powerheads etc. No place is save of them. Getting every single one of them out of your system without nuking your tank and basicly starting from scratch is impossible. - The lack of natural predators makes them a trouble to deal with on your own. You need to remove them manually, but as I said before, if they are growing behind your reef or in places you cant reach where you have no chance in getting rid of them. - They multiple insanely fast and grow really quick. One single snail can produce hundreds of eggs. - They steal calcium out of your water that other corals need in order to build their tubes. - Here comes the worst part: They destroy your corals...by spitting out a net made out of mucus. Small particles get traped inside that net and they retract it back to their mouths, eating it. The problem however is that this net is irritating other corals. They irritate the corals to the point where they refuse to open up and wither away or bail out. You would have to manually check every single corals day after day to make sure there are no snails next to them. - Their calcified shells are very sharp able to cut your skin and making your bleed. Annoying when working on your tank. What you are able to do: - Bad news first: You will never get rid of them. Either give up your tank and start from scratch or accept that they are inside your tank now. Sounds hard, but you need to be prepared for the worst. - Take pliers or any kind of sharp object, locate the snail and smash it until nothing remains of her. You need to make sure to completly destroy the shell. Dont give it a haircut by cutting off the top you need to completly destroy the snail otherwise it will come back. - Glueing the opening of the snails tube shut will make it starve to death. Similar to the option above you still to manually find every single snail and close them off. If you have smaller kinds of vermetids, this will be a pain in the butt. - If you are able to remove parts of your liferock where they are on, do it and completly kill that rock using bleach, hydrochloric acid or vinegar. Its the fastest way of dealing with them. They are immune to dips so giving them a freshwater bath or using hydrogen peroxid is completly useless. - If you are keeping sps corals like pocillopora or acros get yourself a coral crab! They are keeping your coral healthy by cleaning off the snails mucus from your coral. That way the snail will not harass the coral and you dont have to deal with them. The crabs will not eat the snails, they only keep the coral clean and healthy. Studies have shown that coral crabs completly negate the negative effect of vermetid snails (NOTE: This only works for sps corals that are able to host coral crabs. Zoas, lps or softies that dont have similar protector animals are not safe) Feel free to add anything to this post if I have missed important informations. Also feel free to add your knowledge or ways of getting rid of them to the discussion. Im sorry if I made any spelling errors. English is not my first language lol

    925 contest tank "Why Be Normal"

    Here's my contest offering, the "Why Be Normal" tank. 6 gallons of pests and strangeness, hopefully attractive. This will be a clash of fw and sw in appearance only. Current Full Tank Shot: [Photo 📸 Here] Contest Entry Picture: Equipment: 6 Gal. Fluval edge with the top removed. 18w nemo light. For now a .5 sicce return pump sitting in the tank, maybe a cheap hob later with live rock in it. Was looking at intank, but they dont carry any. Bdbs from Tractor Supply Dragon rock and other fw type rock. Spiderwood Livestock: Local caught mojano and other oddities, glass anemone, xenia, caulerpa, and one feature item tbd. Not sure if a local caught fish or shrimp will go in it, but probably if I take time to catch something. Today I aske the lfs for a ziptie in their system covered in aptasia. They thought I was joking. What a beauty!
  3. Hey guys! So, I recently had a disaster in my hobby. My apartment had to be treated for pests, and I was required to remove all of my tanks from the apartment during treatment. During this time, I ended up losing about half of my livestock - including my beloved Peacock Mantis Shrimp. I do really miss having a mantis shrimp - they such cool little creatures. Very interactive, inquisitive, and always getting into some sort of trouble in the tank. Reminds me of my puffers, in some ways! But I don't think I want another peacock right now - I want to try a different species. One I've had my eye on for quite a while. The Wennerae Mantis, Neogonodactylus wennerae! These guys max out at around 3", and are perfectly suited to small tanks. They're smashers (meaning they have modified claws to break open shellfish), just like my peacock was, but with much less power. These guys are able to hunt down crabs, shrimp, and snails, but are going to struggle to crack open anything with a thick shell. I went to my LFS today, and picked up a 5.5 gallon Seapora glass tank for $16.99. It's a nice tank for the price - Seapora makes nice stuff, IMO. I rinsed it out, just to get any dust out of it, and this was it. Next, I decided to paint the back black, since the tank wasn't going right up against a wall. I taped off the rim of the tank with duct tape, cause that's all I had lol. I just use some Krylon Black Acrylic paint and a roller for this. I prefer spray painting but I don't have an area to do that here, so rolling paint on is the best I can do. It looks fine from the front side of the tank, but usually looks kind of "meh" from the back. First Coat: did three coats total, which got me a decently opaque surface. This is what the tank looked like, pre-fill: I added some sand from the Peacock Mantis tank, which has long been dried, but not cleaned. I'm hoping all that dead gunk in the sand will help get us a strong cycle in this tank. Whenever I filled it the first time, I ended up getting milk, basically. Gotta love aragonite. I had just used plain freshwater to fill that time, though, so I drained the tank and added in the rock. I'm using a piece of marco dry rock that I had from a previous tank, a piece of well-seasoned rock that's got some life already on it (although, not much algae due to being in a bucket), and a piece of rock I got from the LFS. I got this particular rock for a reason - but that's gotta be a surprise. Whenever I refilled the tank (with saltwater this time) I was careful to do it slowly to minimize cloudiness. The powerhead I bought (Aquatop MCP-1) was way too strong for this tank, and was blowing water around. So, I pulled my Koralia Nano 240 out of my 10 gallon QT, and switched them around. Each tank is better off, I think. Then, I tossed in a preset heater and a thermometer, and we're off to the races! I'll update this post tomorrow, and tell the story of why I picked this rock, and what the extended plans are for this tank.
  4. Hey guys, Now that my pest tank has matured a bit (it's been up for 2-3 months), I'd like to add something other than CUC members. The tank was setup with a Wennerae or Smithii Mantis in mind, but honestly, I think maybe I'd like something (or some things) that are a bit more active and less shy that mantis shrimp. My peacock mantis was awesome, but I think I want something different after thinking about it for a while. The tank has a very healthy population of bristle worms, pods, and other assorted fauna, but nothing that's out and about during the daytime other than a handful of hermit crabs and aiptasia. Does anyone have any suggestions? I do have some macros that I'd rather not see eaten, but they can be moved if someone suggests a crab or something that just blows my mind.
  5. Hello all, So I know that this guy has been in my tank, I've seen glimpses of him when the light has been on and more active at lights out of course, but never this active! I noticed that he was worming his way around for at least 10 minutes. Can't tell if this guy is harmful or not....I'm leaning towards safe? Pictures attached and a youtube link. https://youtu.be/Iu4Wwt9K_4I -Kpatel28

    Unknown worm

    Good morning everyone Just noticed a few of these worms hanging out on the glass of my aquarium. Does anyone know what they are and if they're good or bad? Been doing this for 8 years and first time I have seen these in any of my tanks. https://drive.google.com/file/d/1LcN6uDv3xzP6Hjwh7SaBx4QPB-0xVNLE/view?usp=sharing

    Invader: Worm? Shrimp?

    Today I discovered something from the gates of hell. I was moving some decor around in my 30 gallon tank, which houses a pair of clowns, a pair of seahorses, and a pair of crabs. I noticed some tiny things swimming around after I moved the decor. I was hoping they would've been a baby seahorses... but instead I got the misfortune of whatever this is. This one was the only one that was big enough for me to catch. At first I though it was possibly a shrimp or something that hitch hiked it's way in. Now I'm thinking it might be a worm of some sort. It's all curled up in the images I've attached cause I think I injured it while I was ~fishing~ it out. It's definitely not a baby crab. It has an elongated figure. Could this be a bristleworm? I apologize for the low quality photos, this thing is seriously tiny and it was hard to get a good shot of it.

    Pest Tank

    Alright, so I'm trying to figure out how to setup a saltwater "tank" that is as little maintance as possible. I have another thread up where I'm trying to use macros similar to how FW tanks use plants, but this tank is just for things that people can't seem to get rid of. I'm hoping that pests and nuissance algae will survive me taking little to care of them. For the last month I've been using a Gelato container (less than 16oz) to house aiptasia and valonia. So far everything has been fine: The valnia does need dosing though. Aiptasia goes through sad periods where it doesn't open up. I don't test anything other than water salinity. I tried adding amphipods, I don't know where they are anymore (probably eaten?). I'll be updating the "tank" to be a little less than a quarter of a gallon. I post pics when the water clears. I would love to get some majano anemone and ball-tip anemone. I'll try adding asterina starfish and maybe some detravores too (most likely bristle worms? they might get too big though). Pest suggestions are welcome!

    What... is... THIS!?

    I have a video LSS: I cleaned my bedroom nano tank of algae, with a water change and in the morning I found this interesting lil guy. Idk what it is, has anyone else ever seen one. Any identification?
  10. I just noticed these a few months back. Have searched for pictures but have not found any. The closest resemblance is a tunicate. They are small approx. 1/8", jelly like, very invasive, spread like aptasia, close up when touched like an aptasia, soft jelly like, I find them on the underside of frag plugs and shaded areas of rock. I've used aptasia x to get rid of them

    Algae I.D. Needed

    Good Afternoon, I went on a vacation for a week and when I came back, my tank was covered in this Algae. It sways in the water which makes me think it is some sort of Hair Algae. Could someone please confirm and give some advice on what to do to remove it? I have been reducing light and majorly reducing feeding to little or no effect. Thank you,
  12. I am pretty new to this. my tank in cycled ammonia, Nitrite, 0. and Nitrate 1-5. I had tiny black worms in my tank, they looked as if they were just sitting on the sand maybe dead. They were a bit thick and only about a 1/4 long. I am not sure what they were I just vacuumed them all out so I dont have a picture. Any idea what they are?

    ID: Ball Anemone

    Found a few of these throughout my tank. They look like an anemone or some sort of mushroom. Any ideas?
  14. Hi everybody, I’ve recently started my very first saltwater tank and purchased live rock through KP Aquatics. So far I’ve been very happy with the rock’s shape and the amount of life that came on the rock. However, during a water change I spotted what seems to be a cirolanid isopod alive and well on the filter sock. Although this is the only one I’ve seen, I want to assume there is more of them in the tank to be on the safe side. At the moment I have added 0 livestock to the tank as it’s still cycling (added live rock and sand 4 days ago), so I’m thinking I could starve them out if I wait quite a while to add any livestock (longer than the cycle)...? I’m wondering if anyone has any experience in this situation, how long starving them out would take (if possible) or if they feed off anything else in the tank that would sustain them even if there’s no fish in the tank. Also wondering if I’d be safe adding members of a cleanup crew once the tank is finished cycling or if these would feed of all snails or hermit crabs? Thanks everyone.

    Vermatid snail(s)???

    For the past couple of weeks, I noticed this thing on my coral that seems to have gotten bigger. When I first got it, I thought it was apart of the coral. I'm guessing this is a vermatid snail with possibly another. Could anyone confirm this, so I can begin the removal process.
  16. Hay reefers! Can anyone help identify this? I know it's a bristleworm but can't tell if it's a goodie or a baddie? Second is should I remove it, it doesn't seem to be causing any damage to corals or tank mates. I ask as some of the other BW's in the tank look similar but not as red/pink?

    Ball or Ghost anemone/coral? Tiny!!

    So at first I thought aptasia, but upon more research, this may be a tiny coral or ball/ghost anemone....IDK. When I say small, this thing is about 1/8” in diameter. Any thoughts? I don’t want to kill it if it’s harmless. 😑
  18. These little anemone looking things with white dots at the center and little fingers around it popped up all over my new live rock on the coralline algae. Anyone got an id? I can’t find anything online.

  20. Saw this thing in my tank today, does anyone know what it is and should I be concerned...... also found a couple of aptasias on my sand bed😵🤬

    Unknown invert in zoa

    I am a new reefer as of December 2018. I have a 16 gal BioCube that was cycled with live rock, live sand, and some crabs. I now have assorted softies, LPS and two seahorses. In the live rock I have seen a bristleworm (yuck!), I think a mini brittle star, and a few snails. I bought the zoa 2 weeks ago. About one week ago the zoa closed up never to reopen. At the same time I started to see little leg-like hairs coming from the zoa. After a week it looks like this! (See photo) I have done much research and finally found what it may be...aiptasia! What do you think. I have read horrible things about this guy (pest). Please advise.
  22. i found this worm its really tiny about less than 2 inches which is too small right now to cause much harm so i will ask now i uploaded a photo its mostly grey-black with a bit of a grey-orange stripe what is it? should i remove it? and what should i do if i need to remove it? and is it safe with inverts?
  23. Anyone know what this could be? It looks like some kind of shrimp and I see 4 of them in my tank. They are super small and I first noticed them months ago when I would turn off all my pumps and they would just be floating on the surface until I poked at them. I do have a cleaner shrimp in my tank but I’m not sure if these could be the babies or something else. Hope it’s not a bunch of mantis shrimp.
  24. M*ther F**ki*g G*d D**Mit! abjkfdsakjf! MEN are is the worst. I have a montipora eating nudibranch infestation which I have been battling for over a month. I am losing the war. First they ruined a white polyp monti, but now they are attacking my prized center piece red shelving monti. Its been with me since I started my tank a year ago :( I thought I was safe when I removed the invested white polyp, but alas, they spread. For you experience reefs are monti eating nudis the herpes of reefing? Are they forever? If i strip ALL my montis out of the tank and dispose of them, how long will I have to wait to starve these F@@kers out? Do their eggs last forever? It seems little is known about there life cycle other than dips don't kill eggs.
