Both are invertebrates and are sensitive. I don't know, but I have a feeling snails might be. But I'm no expert.

Hmm..I had an 'event' the other day with my CO2. My gobies' gills were scarlet red, and they were gasping at the bottom. I lost two zebra nerites, two olives, and a green lace shrimp. My guess, with copper..both are equally sensitive.

If you're thinking about trying to add copper to a shrimp tank to kill snails ... I wouldn't suggest it.

Oh God no NEVER. Im just thinking ahead, or actually in Hind Sight, my shrimp tank, was given to me free and i did clean it well with bleach when i got it, and rinsed it to death, Added Declor and rinsed it some more, but i got to thinking after i put my shrimp in that i do not know if the tank has ever had copper in it or not. And the reason i asked the question is that i have a TON of snails in the tank that are thriving and breeding. So kinda a IF everything dies again and it wasn't a Chloramine problem could it be copper leaching, but if they are equally sensitive the snails should have long been dead.But then again the Chloramine that i Think killed my first batch of shrimp should have also killed the snails. so im a bit confused.

dont worry about it vance. The copper in a used tank IMO 99 times out of 100 even if it was treated in the past is not enough to make a real diffference

Still leaves the question, What killed the last batch of shrimp and why were the snails unaffected? I mean maybe im over thinking it but if it was Chloramines (i was using Wardlys at normal dose and a double dose is required for chloramines, im now using prime) Why didn't the Chloramines kill the snails.
It just doesn't make sense what could kill a whole tank of shrimp but leave all the Snails completely unaffected?

Did you cut any plants or add new ones? I had a tank wipe out after adding anubias nana petites and didn't know better about plants then. Now I soak them and rinse them for a day or so. It's possible in my case, the seller had used something to clean the plants before selling them. I think shrimp could possibly be a tad more sensitive. Depending on what kind of snails you have, ones with a foot might close up until whatever irritant is removed.

Nope all that is in the tank is some moss, that is all that has ever been in that tank, no other plants because i want to see my shrimp lol. And it was the moss they were shipped with so if it was the moss wouldn't they had all been DOA?

Unless that Calcium Hydroxide is what killed them, but i still cant see simple calcium killing shrimp. It just dont make sense.It is the Same Calcium that is used by reef keepers all the time and SW is extremely sensitive.

I have read of others killing shrimp with too much CA. They don't need it that way, just make sure their diet is good and they will get enough Ca that way. Do you even know for sure how much you were adding, or rather what effect it had on the parameters?

That's the thing it was a Very weak solution. and a very small amount added.

the Solution was 1 teaspoon Mrs Wedges Pickling Lime in 1 gallon of water(i used distilled water)


I added 5ml of this to a 10g tank, and 2ml to my 5g tank. within 3 days all the shrimp were dead.

The amount should have been trace at best, which is why i just dont get it.

Maybe someone that knows fw parameters best can tell you, perhaps adding Ca in this way affected the PH. Sudden or dramatic PH changes can kill.

Snails are rather resilient; many people on this board have posted that they boiled or baked substrate, left it out in the sun for a year, and/or soaked it in bleach and the snails survived.

When the first shrimp died i tested the ph it was the same, unless it spiked and then dropped and that caused the deaths.
