hi all! i recently got some jumbo mystery snails off facebook marketplace and added them to my planted tank (this is just a holding spot, they will soon have a snail jar of their own). they were all very active following acclimation and introduction to the tank but over a few hours they started to recluse into their shells.

its been about 10 hours now and all of them have either gone into their shells or have stayed at the top of the tank. i believe they’re all still alive but seem very lethargic.

any insight on the behavior change?

update: thank you for all the help! i should’ve done more research before taking them. i will be rehoming them!

Every time I look up, he’s climbing a tree or hanging to the underside of a leaf- I had no idea snails liked vertical adventures 😂

I had some mystery snails back in high school, but never out live plants in the tank- these guys seem to love crawling along the pothos and I’ve had no issues with leaf nibbling

bladder snail who must have gotten crushed at some point? As far as i can tell there's no bare mantle(???)

Also what are the little tufts on him? He came from a low low end brackish tank, but has been in fresh water for like. 5 minutes

(Tank photo and snails for fun)

I see a lot of people rave about it for keeping shrimp and snails, especially nerites who usually only eat algae and biofilm, but when I look at the ingredients, isn’t this stuff that a lot of regular foods (and probably also animal waste, decomposing plant matter, etc) already have? I get if it’s just convenient to dose, but I’m wondering if anyone who maybe knows a little more about the science behind how it works/how biofilm and microflora forms in an aquarium could enlighten me

Is this something to be concerned about or just a potential bruise? Maybe a nip from a tankmate? (Also meet Gloop). TIA

I've had three nerites in my tank for going on 5 months now and never had any eggs, I thought I lucked out and got three males. 😭

I recently purchased a few red root floaters and after a week now I noticed these new friends in my tank. Should I keep or re home, I already have a nerite snail in this 10 gal tank.

Ordered a mystery snail over the internet and it got here today! It was only in transit for a couple of days and only sat on my step for about an hour in the shade. Opened it up and it's very tucked into its shell and has feces piled onto its shell from being wrapped up. Did a smell test and am acclimating now.

Do you guys think he's okay as long as he passed the smell test? 🤞

My main tank is full of tiny ramshorns, during a water change my syphone must’ve picked one up ( i don’t know how many weeks ago) and i used the old water in a bucket with old plants i’m using to cycle a sponge filter. Today i noticed for the first time the snail in the bucket and it was WAY bigger than the ones in my main tank.
Is that because in the bucket it had more food being the only snail?

Then realized, he was munching on a sinking pellet in the corner.

Tank size: 25L

Other tank members: A colony of neocaridina shrimp. (Currently ~25, but there's 2 berried and 8+ saddled shrimp).

I feed Bacter AE every week.

Area for algae/biofilm:

-Driftwood,

-Lava rock,

-Catappa (Indian Almond) leaves,

-Alder cones,

-Pre-filter sponge 😭?

-Ambulia,

-Ludwigia super red,

-Salvinia and Amazon frogbit (not sure if I should add these or not, as I've heard they can slow down algae growth, so I would appreciate advice on this aswell).

-A carpet of pearlweed/marsilea hirsuta, (Haven't decided yet).

-3 Pots of anubias,

-2 cups of java moss,

-1 cup of Christmas moss,

-7 (yes, 7) Cryptocorynes wendtii brown,

-A couple of bucephalandras mini red.

Why I'm thinking the snail might starve even though it's smaller than the regular nerites, is because of the shrimp. Will they eat all the biofilm resulting in no food for the snail, or will they be fine together? A lot of area for biofilm and algae, but still want to be sure.

Thanks, God bless!

This is Abraxos. I’ve had him/her (not confirmed) since early June (for ease I will refer to him as him).

He’s in a 4ft (120 gallons/450 litres) heavily planted tank. There are other Mystery Snails who are all ok. About 3 or so days ago, I noticed he was super withdrawn into his shell, so put him in his own container in the tank. Everything on him looks shrunken, and I’m not sure what’s going on.

There is a regular rotation of veg, algae wafers, snello for food. Temp is about 26C, PH around 7.6, nitrite & ammonia 0 (I need to retest for KH etc).

It's looking discolored. I think that's a flake. Is this a calcium deficiency thing? ☹️

sorry for bad quality pic but it's in a strange place to phograph

in the tank I have faunus ater, thylomelania sp., ramshorn, bladder snails and brothia herculea, but main suspects are thylomelania and faunus

Hi! I’m fairly new to the aquarium hobby and would appreciate some advice about my nerite snail.

I have a roughly 25L aquarium that was cycled for two months before I introduced 10 Neocaridina shrimp and one nerite snail about three weeks ago.

Since then, the nerite has been constantly moving around the tank, grazing on pretty much every surface it comes across, including the glass, substrate and rocks.

However, since yesterday, it’s been staying in the position you can see in the photo and video, seemingly digging into the substrate. Interestingly, I fed my shrimp a protein pellet in that exact spot yesterday. Could it be looking for food, or is this normal behaviour?

I’ve never seen it stay in one place for this long during these three weeks, so I got a little concerned. I’ve read that nerites can sometimes bury themselves, but I’d really appreciate hearing about other people’s experiences, especially from more experienced keepers.

Thanks in advance for any advice! 😊
