Can't keep snails alive

I posted this on a snail forum hoping that someone would have an idea but haven't heard anything so I'm going to post it here too. Too long to re-write so I'm copying and pasting.

I get my snails from Pet Smart. They were labeled "Mystery Snails". The first ones I got lasted pretty long even though they were in a cichlid tank - they even laid eggs. This was before I knew that cichlids like snails for lunch. That was several years ago. I never got anymore because I had only cichlids and I'm really not into animal cruelty.

I've now developed a community tank (20G) for my granddaughter that has neons, black neons, one glo light neon (got it by accident), and a new female beta. For some reason every snail I get dies. I love these little guys and it breaks my heart each time.

I thought that it might have been because it was once a cichlid tank (I kept two convicts in it for a while until I got tired of dealing with the hundreds of babies) and I used to keep a little salt in the water to maintain an electrolyte balance. I thought perhaps some of the salt had crusted on the top of the tank and the snails might have gotten into it.

So I cleaned the top of the tank; took the filter out and cleaned it completely as well. Put it back in and bought a couple of blue mystery snails. A few days later, one was dead and the other was floating. I thought it was dead until I touched its "trap door". It retreated into its shell so I let it float. It was doing well for several weeks and today I realized it was dead. It had doubled in size so apparently it had been eating but I have no clue why it died.

Additionally, my other tank (50G) has three parrot fish, several long-finned danios, three emerald corys, and one rubber nose pleco. I had four snails in that tank and they were doing fine. Unfortunately, my oldest parrot developed some kind of parasitic infection that most could only relate to hole in the head so I had to teat the tank. Worried that my babies would get hurt by the treatment, I put them in the other tank thinking it was okay now because the one blue was still living. Today only one snail is still alive and that one barely. (Edit: This was the blue that was the last to die)

I just don't know what's happening in that tank. Strangely, when I had the convicts in there I had had a snail in there as well and it also went so far as to lay eggs. Unfortunately, it had a split in its shell that never mended. I have only just realized (reading through some of the posts) that I can put a cuttle bone in the tank to provide calcium.

Is it possible this was the problem, that they weren't getting enough calcium?

I would like to keep them in the tank because their antics are fun to watch but they also keep the tank clean. However, I don't want to put them into a death trap.

Anyone have any ideas as to what my problem might be? I monitor my water parameters but that's mostly for the fish. The only thing I can think of is that the pH runs acidic. However, I read somewhere that the pH wasn't that important. (If you ask me privately, I can tell you where but don't want to cause any problems for the person responsible)
 
What are you exact water parameters? Snails can be very very sensitive to nitrate that is tolerable for fish. They also cannot tolerate alot of the meds, and some of the meds can be residual in a tank. Also, another posibility, is that alot of the snails sold in pet stores are very mature, almost full grown, and not always healthy. Apple/mystery snails have a relatively short life span of a year or two. Calcium issues would be evident with brittle/thin shell growth, irregular ridges, or holes in the shell. Snails can tolerate some salt, so i doubt that is the issue. Wish I had a clear cut answer for you!
 
I tested just now so I could give the correct parameters.
Tank temp: 75F
Ammonia: 0
Nitrates: 20ppm
Nitrites: 0
GH: >75 <150
KH: >80 <120
But the pH is low - off the scale low and the scale goes down to 6.5.
What are the optimal water parameters for snails?

There hasn't ever been any meds in that tank so that wouldn't be it.

I'm not sure about how brittle because I don't handle them unless their floating and then I'm always very gentle. I accidentally killed a pet bird when I was very young (four years old) because I held it too tight. Thus, I tend to hold any small living creature very delicately. However, there are what I would call growth rings and the new growth shell doesn't look as dense as what was there before. Would this be a symptom of a calcium deficit?
 
It very well could be, there are several options for supplementing calcium. You can make calcium rich foods, you can add cuttlebone, or you can dose liquid calcium (diluted and careful not to hit your little critters) at the marine dose (Kent's is good). Although 20ppm of nitrate is fine for most fish, snails seem to appreciate even lower numbers. I do huge water changes 2x weekly for my snail tank. I don't really see anything obvious off with your numbers or what you are doing. Perhaps its the source of your snails. Don't give up!
 
20 ppm is where I usually change the water. It's a small tank so things can go wrong a lot quicker than in a larger tank.

I won't give up but it breaks my heart each time one dies. I think I'll be more particular choosing which snail to bring home. I'm going to try and find someplace else that sells snails. I haven't really seen any but then again, I haven't really looked.

I like the idea of a cuttle fish bone. We used to keep them in our parakeets' cages. :)

Thanks for your help. I kept thinking I was doing something terribly wrong but couldn't figure out what it was.
 
:iagree: H3D, that was my though too.

Calcium could be the issue but that usually doesn't result in behavior issues like you described, TheCat. Generally even a snail with a big ol' hole in its shell will continue on happy as can be. Food though, it could be a food issue.

I'd also agree with what msjinkzd said about Petsmart snails. They're usually old and often sick due to lack of food, fish harassment, poor shipping conditions, etc. When you're going to buy them, you want to buy snails that are actively moving. That's the most important part. They should be moving and not all sucked up into their shells. Look for smaller snails, as those are generally (not always, but generally) younger, and individuals with all their tentacles. Also look for smooth, even shell growth all the way up to the outer edge, and little or no erosion at the oldest part of the shell.

If you buy healthy snails you will have a much better chance of keeping them alive and happy! Sorry to hear you've had such a bad time of it. Don't despair though! :)
 
i had mystery snails too untill like about 1 to 2 months there dead well and of course there from petsmart i guess maybe petsmart sells them to old??? idk im just keeping tadpole snails and trumpet snails that came with the plants and there fine they help me alot with algae
 
Go with adding a full cuttlebone to up the ph. It also gives the snail(s) the chance to munch on it, if they're so inclined. I usually brake a full cuttle bone into 2" chunks and spread them out in the tank.

Another thing that could be happening is metal toxins. Check for as many metals as you can, in particular copper. If you ever used pesticides/medications or fertilizers in the tank to house snails, the chemicals in those products can be extremely harmful to all invertebrates.
