Killer Assassin Snails - Shrimp Keeping Myths

Assassin snails killing shrimp? Do adult shrimp kill baby shrimp? Check out the video and find out what we've found on these two shrimp killers.
Let me know what you thought of the video and if you agree. The shrimp keeping hobby is all about education and the more we know, the better we can keep our shrimp.
With over 100 shrimp tanks, I believe what I said to be true. We have experience these example for pet shrimp and hope to help other avoid mistakes. Have a great week everyone and see you at the live stream!

Been keeping Assasin Snails for years in my tanks, never seen them attack any living shrimp or suffered strange losses within tanks stocked with Assasins. They only eat dead shrimp, dead fish, but most random was to find one eating a dead houselfy; which somehow managed to get under the aquarium hood, then drowned and sunk...

[@xanderkaz8927]

Maybe the assassin snails were eating the weak shrimp so that's why the colony was the best

[@StevesRealWorld]

Very good point!

[@sofiakaos5278]

That was my first tought at first but no the snails prob ate plenty of baby shrimps in between the bigger ones whatever comes close to them they eat if its meat

I keep Reds, Oranges and Amano Shrimp in a tank with Trumpet snails and Assassin Snails. Heavily planted low tech tank, no issues whatsoever. I've seen the video where one attacks a shrimp but that shrimp was mid-molt (or dying, I forget exactly) so it was a unique circumstance they blew out of proportion.

Hello! Great info, love the channel!! I have a 45L aquarium, where I keep nano fish and neocaridinas. The fish don't hurt them but they keep dying. I have lots of plants, wood, moss, everything should be fine. I don't understand what goes wrong. Could weekly water changes kill them? I change about 20% every week. Hope you see this and answer. Many thanks!

[@MusingsFromTheDen]

Do you also keep shrimp in a peaceful community tank with fish? I just got my Amano's about 2 weeks ago and was wondering if there are particular rules that do and don't apply of you're keeping a community tank rather than one that's solely shrimp. 😊

Hi just found your channel - loving it! I am really new to keeping a tank and need advice, thank you in advance; its 70lt 2 months old i had a really small one and only one black moor. i decided to go big lol. substrates, plants and good filter. one week ago i added four amano shrimp and 2 assassin snails. They were bought from the same shop and the exact same tank.The shrimp have completely disappeared, where are they? Can anyone advice me. Ive just watched your other video on shrimp escaping and have just checked all around the outside of the tank

[@alixxworkshop846]

WOOW!!! I didnt know that Anatome Helena eat shrimps... I've seen mini puffer fish eating them and Molly's nut snails? This is a good to know,THANK YOU!

[@breedingfauna3732]

If you want to prevent this aggression between shrimps, I witness it too in my CRS tanks, try to crush your food. Do it with a spoon or something, and place the food on an oak leaf or something if you have a soil so it doesnt sink into your bottom. This really helps. Food for babies needs to be dust, I do it 2/3x a day and it really helps. I have had like 300 shrimp now from 5 CRS females within 3 months... All have grown up nicely and are nearly adult.

[@jetjazz05]

There's a couple videos on this channel about Bacter AE, that stuff is pretty awesome, my shrimp all love it and it's a fine white powder that's supposedly dried up biofilm, when you put it in the water it clouds it up with dust sized particles and the shrimp literally don't even have to move, they just catch it as it drifts through the water or as it lands at their feet. This food in particular has been impressive to me because I haven't seen a single shrimp on shrimp aggression since I got the food. It's expensive, 25-30 us dollars depending on where and when you get it, but a 70 gram jar will do ~140 spoon full feedings, although unless you've got more than 50 shrimp you really only need half a spoonful, so you can get 250 or so days out of $30 worth of it, so for me it's worth it.

How long do ghost shrimps live?

[@kapil509]

RCS and assassin go along just fine. Assassin snails are widely misunderstood they only eat what is dead or dying and of course other live snails.. My snails don't attack my RCS ...this is a fact I had 8 shrimp and three died due to water parameters I added snails after that and I have not seen a dead shrimp since then. The hollow skin which he discussed is actually exoskeleton which shrimps keep on removing from time to time and yes assassin snails will eat those exoskeletons

[@nayanshakhawath6543]

Is Anubias plant harmful for shrimp?

[@huyquoctran2088]

They do kill and eat shrimp but rarely happens since they are too slow to catch them. The one got eaten are Mainly the slower and weaker shrimp. Seen it before.

[@tapewormsandstoplights2868]

In my 55 gallon I had a huge breeding colony of RCS. Farther along the road I had a very large bladder snail explosion so I got 3 assassin snails. The assassin snails laid eggs and there were over a hundred of them. After a short amount of time all of the bladder snails were dead and the assassins needed some food, so they started going for the shrimp. There were lots of plants that the snails had trouble navigating, so they struggled to get the shrimp and almost all of the snails died. I actually ended up making some necklaces with the shells of the dead snails. Even after all of that my shrimp are doing better than ever.

[@annhorn1190]

Are there any plants that should not be put in with shrimp?

[@T0tenkampf]

I love all the comments here of dudes with a 20 gallon aquarium telling this guy that he is wrong about assassin snails right after he mentions he has 100 shrimp tanks and 30 assassin tanks.

[@stealth5508]

Exactly! Agree with you. I recently put 2 Assassin's snails inside my shrimp only tank. A few days later, I had a hollowed out shrimp with water fully inside. Tried querying about this in a few forums and didn't get any response. A week later noted another shrimp dead. This time noted that the shrimp was stuck to a goo or mucus like substance. I remember seeing this on the foot of the snails. Promptly removed the snails for good. So it is a myth that Assassin's snail cant catch a shrimp. It can do so if it wanted to - using its goo.

If you know how they actually kill snails, you understand that they are no danger to active animals like shrimp or fish. They do eat dead or dying shrimp, which actually is a good thing.

The Anubias myth came from a youtube video where a guy had a tank stock full of CRS and he rescaped with ALOT of anubias cuttings and then the day after hes tank was a total graveyard. Dunno wether it was the anubias or someting else but it was sad to se.

[@heatherwanderer777]

guess it depends on if he bought the anubias from someone, and it might have been contaminated, or if he had it in another of his own nonshrimp tanks and he was using non shrimp safe ferts on it in the other tank. Lots of ways that it could have happened that had nothing to do with the plant cuttings themselves. But thanks for sharing cause I'd never heard about the Anubias myth til today.

[@travishemming3783]

I've only had shrimp for 11 days now. I got a neocaridina mix of about 80 shrimp, and some came berried. On day 8, I noticed the first babies. The next day, I had just fed and was enjoying watching them eat. A large one comes along on a leaf and picks up a baby, and it looks like it's rolling it around near its mouth. Having read that neos don't eat the babies unless they're really starving, I keep watching, expecting the little one to appear somewhere close by. I never saw it again. With all those legs moving, it was hard to make out the details of what was happening. So while I'm not completely sure it was eaten, it sure looked like that's what happened.

Hi Rob i get a lot of trouble with high nitrates what ca changesn i do to reduce this without water ?

@@LupDiesel That is extremely bad advice. A fully cycled tank will always have nitrates! Ammonia is converted to nitrite, which is then converted to nitrate. you do water changes or add alot of plants etc to help lower the nitrate level.

Hell yes Assassins eat shrimp :-( I introduced 11 assassins into my community tank after it got overrun with hundreds and hundreds of pest snails. I had a very healthy population of breeding Rili shrimp in the tank as well and they were constantly breeding. At any one time there were 3/4 different sizes of young shrimp in the tank. Same as you, I found one or two empty shrimp carcasses and did think about the assassins but brushed it off. Unfortunately I couldn't move the shrimp into my other tanks just as a precaution as they have fish in them that will definitely eat them. Long story short-they absolutely annihilated the pest snails, my tank was littered with many hundreds of tiny empty shells within a cpl of months. They have also completely destroyed every single shrimp in my tank!! There's lots of baby assassins of various sizes as well. Absolutely gutted as my shrimp were breeding so well! :-(

[@marthanewsome6375]

My neo's are housed with my cardinia's and they fight over food and neo's always win. I have a suspicion that neo's can kill cardina's. I kept finding dead cardinia's right after feeding. So, now I give them food in several area's of the tank at once and also sprinkle some baby food in. Ever since I've done that, the fighting has cut right down and no dead cardina's. It was funny because I was blaming the endlers at first and were going to move them out, but it wasn't them at all and when I saw how powerful the fights got between the two species, it clicked that must be it and it was. The endlers stay at the top of the tank and eat flake food, they don't even bother with their own babies.

[@augustvukosovich4683]

Wow, that is fascinating. I've never seen food fights in my shrimp tank. I wonder if there is something that causes it?

I had about 15-20 ghost shrimp. Had 4 assassin snails. Or I thought I did. Turned out to be around 10. I put in feeder snails for the assassins. I figured it would be enough to keep them going for a while. Also had some mystery snails. My assassins cleared out all of the feeders(ramshorn), three mystery snails, then my ghost shrimp started disappearing. Yeah, they'll eat shrimp. I've been told it's rare. Apparently I got the aggressive gene pool in my tank.

Thx for a great video, I'm just starting (1month now) and find it all a bit overwhelming. I'm totally in love with cherry shrimp and I think I may have broken every single law in the book in my shrimp set up - zero tech... but I need to start somewhere. But why I'm writing here: Anubias are of the Araceae family, like Pothos (Epipremnum of various varieties), Pothos is known to be poisonous to man (I think this includes women lol) and beast, I even saw a video where a youtuber removed all Pothos from his tanks cos he came to believe it was killing his fish... could this be the reason for the birth of the Myth? In my little tank i have a pair of micky mouse platies, the guys at my local fish shop decided it would help speed the cycle, and they told me to keep pothos or simmilar growing of the edge as well as my other plants in said tank. I have a cutting of a pothos and a cutting of a monstera adansonii on the edge, both have a root each at about 2" long, the platies are fine. and my goal is to get blue shrimp in there. once again, thx for a great series about solving myths. 👍👍👍
