Mysterious Shrimp Deaths

Okay, so I've had a cleaner shrimp for a few weeks when it suddenly died. After testing water, I determined it was an unknown natural cause of death. So, I bought another one yesterday. He died today; I found a nassarius snail devouring him. So now I'm beginning to think, is there something I didn't test (I don't have a nitrAte testing kit, fresh out)? At what reading do they die? The specific gravity is at 1.022, is it too low for them? Is that the cause? I just can't seem to find the cause, so hopefully one of you can. The peppermint shrimp which I bought with the newest cleaner is still alive, so I am very confused. How hard is too hard of water for shrimp?
Many thanks.

How are you acclimating them?
I have had shrimp just up and die on my also. Cleaners and fire shrimp. My thought is a lack of iodine/iodide, but I haven't tested this yet.

I use a slower version of the turkey baster method. Half a baster store water out, half a baster tank water in every... 10(?) minutes. But I would think they would have succumbed to shock a lot sooner than a couple of weeks (or in the last one's case, a day).

i have a fire shrimp, when i first got him i turned off my lights, placed the bag in the tank for 3 or so minutes, then put in 5ml of my tank water into the bag every few minutes or so, i only acclimated him for about 10 min or so then let him in. he's doing just great 3 weeks later and has shed his shell twice already.

i just got a clown today and did the same w/ him, he's doing great. he's been putting flakes in his mouth and spitting them out making a mess in tank so im going to try some brine shrimp later tonight.

there must be something major wrong w/ your water. do you have any inverts in your tank? if you have crabs or so and they are doing great then there is no reason why your shrimp should die.

i test my water for ammonia and nitrite every once in a while, and do water changes through out the week. i add some kent dKH powder stuff, just a tiny pinch of it sometimes, i dont know the levels of calcium or anything or w/e but my coroline is growing crazy and my fish love to eat all the food i put it so i think my tank is fine.

you may want to do what im going to do in the near future, im going to buy a sea urchin, im thinking a pencil urchin, from what i hear, they will loose their spines when the water quality is bad, which will give me time to check things out and fix the water, its a great visual of water quality. the spines grow back, and that warning can pay off if you have expensive live stock.

Yeah, I have crabs and a peppermint shrimp and the appear to be doing fine. The urchin idea sounds pretty smart.

I think regular testing would be easier than waiting for their spines to fall out. I have a pencil urchin and they do shed spines, even with great water conditions. If you get one, make sure your rock is secured because they sometimes like to wedge between rocks.

Looks in good health. What I don't understand is, my first cleaner shrimp had molted once, so I didn't think their was an iodine/iodide defficiency. And then would that affect them as quickly as a day?

Sometimes they have a bad molt, or get caught before their shell hardens.

I'd think there would be bodily harm though. I watched mine stagger around the tank bottom for a few minutes, without any injury to him and then he just lay down and died.
