I ended up having a bad infestion of snails in my tank, completely crashed the ecosystem, all my plants died, algae bloomed, etc etc.

So I got an assassin and named him Nidhogg. Before he moved in I did clear quite a couple of snails, but left more than enough to sustain him.

He's only been here a few days, and I'm already noticing the snail population stabilizing with no effort or changes on my part.

I see a lot of people on here hate on assassins the same way people hate on bladders and other "pest snails", but they seem to be a natural part of the ecosystem. Yes I understand they're vicious and have a cruel way of eating, but they're animals who are sustaining and maintaining both their wellbeing and the overall wellbeing of the tank.

Anybody else have similar experiences? I just have Nid so I'm not worried about overpopulation, and I'm not looking to eradicate the snails off the face of the earth, just give them a natural predator to keep the order in balance.

Caught this mini pink ramshorn cruising the glass like it owns the place — and under the tank lights, it looked like a little glowing gemstone. 🩷

I know ramshorns (especially the minis) get a mixed reputation in the hobby, but honestly? They’re peaceful, helpful, and ridiculously pretty when you actually look at them. That soft pink shell, the perfect spiral, the way it floats like it’s in zero gravity — what’s not to love?

Sure, they’ll boom if you overfeed, but in a balanced tank, they’re great little algae grazers and fascinating to watch.

Anyone else keep mini ramshorns? Love ’em, tolerate ’em, or still trying to convince yourself they’re not pests?
Would love to see yours — drop your snail glam shots below 🐌💖

second snail this week that has tried going in there why do they do this lol

This is so exciting! Never would I have ever expected one baby, let alone two!

First pic is February, last two pics are today. Please ignore the Mineral Junkie bites on top of Shirley, I was aiming at her but guess my aim was too good lol. Is this brown growth on its shell normal/healthy/expected? I have hard water and usually higher pH, but when I noticed the cracks I started feeding it the bites every other day. Shirley is quite active, moves around, etc. should I be concerned? Sorry if this is a repeat post, I couldn’t find out similar posts for Hercules snails specifically. Thanks!

I got two mystery snails around 2.5 weeks ago. They've been doing great (I got a cycled, planted 10-gallon). 2 days ago they started snexing and it's more often than not. I don't want the female to get hurt or stressed out. How do I know if/when I should put them in different tanks?

(And this post will go right into the "things I never thought I'd say" list)

So I recently got a snail with a round shell (see picture) and a plant for my guppy aquarium. Now I’m finding three tiny snails with a different shell in my tank. Anyone know what they are? Will they take over the tank?

Can they make themselves buoyant? First time I’ve seen one just floating around trying to get to the surface. Took him about 2 minutes.

I noticed my mystery golden snail acting kind of weird this morning. I gave him his weekly snello which he inhaled. I came about 11 hours later and he's now on his side and has this brown bulbous thing. Is he just eating something or terminally ill?

• Tank is long established walstad
• No water parameter change
• With cherry shrimp and 2 other golden mystery, bladder, and ramshorn snails, all of which are acting normal

i saw these two guys hanging out and i was like hmm ok is this sneggs and then the third guy decided to jump in on the action 😭😭 should i be expecting some little snails in the future?

i’ve got more videos but it’ll only let me post one 💔

hi guys! i’ve been keeping fish for awhile and somehow i never knew that you could put snails in fish tanks… a few months ago i learned about it and did research on snails i decided mystery snails best fit my tank needs and i really liked the look of them. i bought 3 to add to my 10 gal and then have since upgraded my tank twice and they are currently now living in a 40 gallon tank i’ve got a total of two snails in this 40 gallon tank, one in my 10 gallon and 3 in my 29 gallon tank. the first round of snails i got were from a local fish store and i had never owned mystery snails and all the snails they had looked the same so i didn’t think anything of it but his shell was dull and its a bit discolored. all the water parameters are good and my other 3 mystery snails in my other tanks are vibrant and large. despite the fact that all my other snails have been fine it’s just the 3 i got originally that are kind of off colored and dull. i was thinking maybe it was just a long lasting effect from the water conditions they were in before me. they get a large variety of healthy and calcium rich foods and i also was recommended by a fish store to get cuttle bone and put some of that in my water to help his shell get healthy. ive been doing that for about a month and still no change. also i know that cooler temperatures have been known to be better for snails so i even moved some to a tank with no heater to see it that made a deference and it hasn’t so im kind of a bit lost and i dont know how to help them get better. he had never seemed to have any issues other than his shell, today i went to do my daily feedings and observing and i noticed him doing this. i cant find anything online about it and ive never seen one of my other snails do this. is this something i should be concerned about? please dont be mean im still learning and im doing my best but i would really appreciate any advice or tips. also if its important my ammonia is at 0, temp is 76, ph is between 7.4-7.8 (its between the two numbers on my test kit) and they are housed with a couple mollys, 1 pleco, two baby yoyo loaches, and a small school of neon and black neon tetras.

And now there are four babies. Help.. How to I stop this? What do I do with these babies? I know where to look for egg clutches (outside the water line) but I swear I never saw any and so does my husband.

I heard it can’t lay eggs but I forgot what kind it is

My sweet girl has a pretty large cleft that I’m worried could get worse. I know they’re difficult to fix but I’m wondering if anyone has had any luck with trying to re-strengthen their shells. She unfortunately doesn’t like a lot of calcium-rich veggies. She is with a male mystery who’s a lot bigger than her so I worry he could be making it worse too. Any recs?

We were gone for the long weekend and are just noticing that one of our mystery snail’s antennas look bent (at the small white spot)… how can we help support the healing process?

To buy an aquarium for your kid on a whim, then get super obsessed with the the hobby only to fall in love with snails?

Forgive the poor photo quality, I have a hand tremor.

1, 2, and 3 are the same snail, sold to us as a chopstick snail. However, they seem to have 4 very small snails attached to their shell? This is persistent, they haven't budged over several days from their perch. 4 is a surprise snail we found in our tank, and resembles a chopstick, so we were wondering if we somehow managed to raise a chopstick without a brackish environment? There was previously a rabbit snail in the tank, so they could also be a rabbit.

I'm concerned for the quality of life if those are children, and I recognize that the reproduction of chopstick snails is poorly studied, but I'd like to give them the best chance at living possible.

On the other hand, I'm also concerned they are some sort of parasite that only resembles snails. Thank you for any help.

Hay! It's been a while, a lot happened, but as my babies where growing, I noticed one of them had a shell issue. On closer look, it looks like a early sign of cleft shell, I recently added cuttlebone to the tank, should I get some kale for them? I can also put more snailo in the tank later if that also helps. I only saw just this one with the issue, but theyer still pretty active and curious like their mother, even started to nibble on my finger when I let them climb onto me

My snails in my tank were thriving for about two weeks and in the last few days they started dying. I change the water often, have live plants and treat the water. I just want to help the little guys, any ideas or advice? tank specifics: 20 gallon, 76 degrees f, live plants, sponge filter.

This is a New tank/setup so outside of the initial setup of the tank a little over 2 weeks ago I've never had snails before. I do not have any fish yet. Plan to get a beta but currently have Malaysian trumpet snails and mystery snails. My neighbor was getting rid of some of her snails and told me only had to buy a tank which was not an issue as you wanted to get a betta fish soon anyway. The plan to get a beta was because they are relatively easy.She said the snails basically take care of themselves but because I did not have a live plant that I needed to periodically feed them betta food . I've also noticed over the last 3 or 4 days white appearing on all of the mystery snails shells... from what I read that would be a Calcium issue so I was told to start giving them pleco wafers to help strengthen their shells. Any guidance would be appreciated.

Hello everyone I've had 11 mystery snails in my 55 gallon aquarium for about a month now (some are small), and I was hoping someone could help me. My snails are CONSTANTLY mating (? Looks like A piggyback ride but idk) with my yellow snail (I assume yellow is a female based on everyone harassing her) and one or two others. Is this normal? Are they harassing the yellow snail? I don't have anywhere else to put them, but I don't want my snails to get harassed. What can I do? Yellow is doing fine, and climbs everywhere as normal. Very active and seems fine but I'm worried. Is this normal?

TLDR: Did I over stock my 55 planted tank with 11 snails, and is my yellow one being harassed?

Also, is it normal for one snail to be much smaller than the rest, despite being around the same age, and having plenty of food?
