[@user-kn7lz5uc9u]

[@brileebaby3969]

I have a WEEK OLD TANK & have HUNDREDS if not thousands😭 I don’t overfeed came in on plant jumped onto a dying plant I was trying to recover and went to TOWN without me knowing til I finally got rid of the plant and while removing it I must of loosened them up off the plant idk bc within an hour or so I saw HUNDREDS of babies allllll over the glass ! If not thousands tbh! I want to cry I do NOT want them in my tank idc what this guy says lol idc if they’re good whatever idc I’m not comfortable w them Will be doing substrate free tank for a few weeks cleaning old Food immediately and also adding pristine by seachem which basically helps remove their food source by cleaning up microscopic bits of detritus you don’t see or can’t get ! I heard copper treatments work some ppl had bad experiences w that though or also certain anti parasitics but idk if I wanna risk my bettas health over it This way WILL tank longer but it’s worth it to not hurt the fish or my cycle So yea ugh he’s eating them too they’re SO small you’d think you wouldn’t even notice them Moving bc I didn’t til I posted a pic and someone in a betta group said worms And I stared and stared close up and saw they were in fact moving and wanting to crawl out of my skin MY TANK IS ON MY NIGHT STAND NEXT TO MY BEDDDD!!!! Where I SLEEP! 😭😭😭😭

[@kimicat4102]

Oh my! I had these worms in my filter of my 2 feet tank. Im very squeamish regarding these types of things. Wearing gloves, I kinda dunk the filter with the wormy sponge in a bucket of old aquarium water several times to 'push' all the worms up. Set it up again and turned on the filter, all the worms came spewing out of the filter hole. My platies and guppies had a worm buffet.

[@alexisthurber6708]

Thank you. It's great to know they're harmless. I saw a few and had a bit of a panic. I read a ton on them and saw that theyre fairly common and won't cause harm to my turtle. But I will be doing a 100% clean up.

Great video, I've never scene them, that's not to say I don't have any. Do they like sand as well as gravel? Pretty much everything I have learned is somehow connected to tank maintenance. Always learning something new.. love it!

[@pigeonman7483]

Ive been in the hobby for years and never seen these little worms ever , I was freaking out once i seen a bunch on my little tank. I think i made a bad move on putting a large goldfish on a 7 gallon tank and probably over feeding it.. kool video👍🏻

[@ibnuazmi9638]

Thank you for the explanation, I just put some substrate in my old tank, within 1 week, they are here. I don't even dare to put my hand in my tank anymore. Now I'm gonna do full water change and throw out the substrate

[@tarzantheapeman1427]

So I just have a little 2.6 gallon betta tank that’s live planted, with two nerite snails, I was told not to siphon the gravel because it’ll uproot the plants...so do I just start feeding less? I do weekly water changes of about 10-20% and I usually just clean the old media with old tank water....

[@RLCAquatics]

Great info!!!!!

[@sphere6258]

My sorority of betas loved them, I just poked a clean plastic ruler into the substrate and wiggled it. The worms would pop out and the betas would chow down. The betas would see the ruler and wait. Maybe two weeks of doing this a few times a day and they were gone as far as I could tell. It was pretty cool watching them hunt the worms.

[@yeryer5945]

Sedona cool so my betta fry can eat them without me worring correct?

[@karlojimena9279]

Is this real? Do they actually eat those cringy worms? I have only one betta(male) in 5 gal tank. My girlfriend saw those tiny worms and screamed like there's a ghost.

[@rogl7969]

by far the best method weekly maintenance

[@KathyaE91]

My tank has a bunch. Would you do a whole water change or keep to the 25/50 water change every week? Any recommendation on a filter for a 29 gallon split into 4 sections for 4 bettas?

[@birdbrain5381]

great video, but I think you should emphasize their benefit and role in the aquarium ecosystem. They are a great upcycling food source. They turn waste into plant food and are a live culture in your tank for the fish to eat. You make the point they aren't bad, but I think they are actually good. A minor nuance, but I am encouraged to see the numbers you say are good during maintenance (3-4). great advice!

[@hugogarcia3193]

thanks I was cleaning my tank and I find this worms. .I was worried about it. thanks for the info

[@whitneywheeler2274]

Thank you for this video. We have mystery snail tanks and we feed them a lot. They are our breeder snails. They crawl on the glass and they are tiny. We did a 75% water change and I vacuumed. There are a lot less. But I do t know what else to do that won't crash my cycle.

[@me9876]

Im cycling My tank and I put some food in to break down, so I have a few of them now ( not an infestation ) is this normal

[@janamartin4048]

Can live plants cause them ( too many live plants decaying)? My daughter has a 5 gallon beta tank with 1 beta and 2 mystery snails. She only feeds the beta what he will eat (one pellet at a time over about a minute) and gives the snails a single algae tablet every 2-3 days. However she has a lot of live plants in the tank. I’m wondering if the plants could be contributing to the worms? Or is she feeding the snails too often?

[@d.s7578]

Thank-You for this video. I knew I wasn't going crazy ahaha. My husband didn't believe me when I told him the thread like things were moving on the glass. It took us 3 weeks to finally get everything right and now the worms. ugh

[@just4fun-family145]

What’s up brotha, Call video thanks for all the advice… Mine are what seems to be the exact same thing that you’re talking about… There’s a bunch in the tank even when the lights on and summer stuck to my Oscars… What do I do to get them off? Also, not sure why this happens because I clean my tank once to twice a week. 75 gallon with a marine land c530 on it and 2-75 gallon sponge filters.I need advice would be great… And will Epsom salt or Prazi pro help?Also my substrate is sand so vacuuming is very difficult… Tips?

[@JamieDunne]

Thanks for the info... I saw bout 20 of these little white worms swimming last time i did a water change.... exactly a week after I left my GF in charge of feeding !

[@QueenCoCoaMocha]

Whew🤯, thanks..at first I thought I was seeing things it was about 3 or 4 I started to freak out. This morning with my water change I saw only one at the top. Theres no telling how many more. But my prob is jus as you said overcrowding, over feeding, not enough frequent h2o changing. I'm going to get another aquarium bc I have 2 baby guppies for my 2 yr old. I'll prob jus split the fish from there and do cleanings on both frequently.

I have a newly cycled tank with some plants, spider wood, moss balls. No fish. No over feeding and I see almost barely visible worms all over the glass when I woke up and they aren’t leaving with the tank lights on. I had to strain to see them. I’m not sure if that is the worm your talking about? I’m freaked out! I’m not sure what to do except to vacuum the gravel and do water changes? Any help would be greatly appreciated. I watch over the tank constantly and do everything I can to have a beautiful tank for fish when it’s ready. But apparently not now :(

[@Fishaholic]

I had some in my newly established tank and I got rid of them by just doing water changes.

Since I've never looked for nor seen this creature, I must be doing some things right. Btw, Excellent upload!

thank you

[@evoxxxbih8386]

Bet you do every established tank has them try this keep the lights on for a week straight and than turn them off for two hours and come back and turn them back on you will see them everywhere.

[@mitchelfisher9422]

Thank you I was freaking out for sure... I have one question though is it bad if the fish eat these worms?

[@SugarMakesMePOP]

very helpful. I have a 20gal freshwater tank. one of my male guppies started acting lathargic and not eating as much. and a few days later I noticed there were a lot of white tiny worms on the glass. I think it's making the water cloudy. I think we're going to try to cut down on the feeding and see if it helps.

[@aidanmccormack5443]

Kianna Silva I’m in an identical situation... same tank, same stock, same problem. Will be vacuuming more and feeding less. Have you had success?

[@blueee4876]

hey dude i have a query. my small fish bowl maybe 2 to 3 liters only has these after my betta died. i cleaned up the betta quickly right after it died and currently there are only plants inside the bowl. basically i have rotala and java fern inside and idk why but my java fern is paling.. the dying leavea are full of detritus worms and the bottom too.. my query is, im gonna leave this bowl for a long time with no supervision, and i plan to make the bowl flourish with plants first for 2 monthd before putting betta/shrimp. should i cleanup the bowl to remove the detritus worms or will they disappear eventually once they eat up the dead plant matter? if so how should i do so and killing as much of the detritus worms as i can and without killing the plants?

[@AriRenee-rl1ld]

Try to clean this fishbowl often, because this will lead to an overpopulating species that you don't want. Especially if you don't have any fish to eat these worms. So if you just want a bowl flourishing with plants, clean it daily or weekly, because the worms can become a huge problem without any of their predators around.

[@katelynmoskal2631]

i have a red eared slider turtle, and just noticed hundreds of worms in my tank! I don’t have gravel, i use to though, i now have sand in there. Will they be able to survive in the sand? Full water changes and partial water changes i can do, but i feel like they hide in the sand so when i put new water in, they show up again but less. Help

[@heynamesraul3697]

[@billnye198]

If it's the worms that come from snails, schistosomiasis or something like that, than they burrow into human skin and work into our bloodstream to travel to our organs where they breed... Nothing wrong with being cautious

[@aquarius9900]

i have had my 10g running for 6 months and i had 1 betta and 4 months went by and i lost her then a month later i got another Betta fish and this time i am prepared for everything im testing all parameters and i only added a floating plant by 123grow which comes in a sterile cup i spend the extra so i dont take the chance of importing parasites but iv had my new betta in my tank for 2 weeks and today i have seen the little worms at the top of my aquarium waterline and i have bin doing 50% water changes every morning to keep my nitrites at 0 because my tank is going thru a mini cycle since it was empty running for the time period that i had no betta but i added a pinch of fish food a couple times to keep some form of ammonia for the the cycle..so i guess its possible even when you dont have more then 1 fish and do daily water changes.. i know now to really dig the sand up and vacuum good... i hope they start to diminish..

[@amyblack5625]

Finally, a recent video about these worms! I have a couple of questions: 1. Can these worms hurt/infect people? I'm pretty sure that they can't since they are supposed to be scavengers that feed on dead things/rotting things... but still. Worms are worms. 2. Say that I am cleaning out my tank with a siphon and I manage to suck some up-- what should I be doing with the water if I can't dump it onto my lawn? I live in an apartment complex in LA on the second floor... So I had always just let the water go down the drain... but I don't want to put these worms back in our water system if it turns out to actually be bad for us. Is there like a way for me to ensure that I am killing them before draining (i.e. bleach, boiling, etc.)? 3. I noticed some worms in my filter. Not a fan of that. How can I address THOSE worms specifically without sacrificing my biological media? I remember reading something about a salt treatment, but since I'm keeping freshwater fish... I'd rather not mess with that. If I do have to, then I will... I'd just like to know how to do it. I have done quite a bit of research on these worms, and I know their function to the ecosystem (it helps being a Biology major), but I find myself still kinda clueless when it comes to actually handling the worms themselves. Should I be sanitizing my siphon every water change? No one really talks about that except with parasitic worms. Thanks in advance. :)

[@AriRenee-rl1ld]

Question 1: No, they don't hurt humans. They feed off of algae and leftover food. Question 2: Yes, you can bleach the tank as well as use extremely hot water, but make sure that you put the fish in a separate tank or a big container first. Once you think you got all of them, you can drain the water. Question 3: You can do the same process from question 2. You can use different types of fish to keep these worms under control. Betta are the most helpful, for they are natural predators to worms and larvae.

[@technoid0405]

I used Seachem Cupramine to get rid of them, I was able to get rid of fully grown dirt worm but was unable to completely remove the younglings. I think I will have to treat the water for a long time. But so far the results are good. If you are considering to use Cupramine, be sure to remove all invertebrates like shrimp etc from the tank as it is poisonous for them

[@ladygoji7754]

Can these be little bity worms on your tank glass? They aren't big at all. If so, I have a lot of them in my new tank, I think I got them from a plant I ordered. How do you get rid of them? Just suck them out?

I have these worms bad right now but I don’t understand how and that’s my concern. It’s a new tank it’s been cycling and hasn’t had any livestock and all new decor so why are they there?

[@anthonyragan2696]

I can honestly say I've never seen these in my tanks. Doesn't mean they weren't there, of course. But, if I understand you right, you're saying they're more of a warning sign of a problem, than a problem themselves. (And water changes are the single best thing one can do for almost any tank.)

what if you don't have any gravel in a goldfish tank...its a 40 gallon tank with 5 fantail goldfish...i feed them the right amount of food. stuck a chill female betta in there with my goldfish. there's like maybe 20 little white flat worms moving on the glass of the tank.

Kathleen Monsegue those are actually planaria and you should probably treat those, flat worms are HARMFUL, most tube worms are good, but no flat worms are

I have a 5 gal for my betta boy. I’ve been fighting these worms for months! I’ve done everything except dose harsh chemicals. Help? 🥺 70% changes every 2-3 days, parameters perfect, clean filter clean gravel.
