You're going to have to include a bit more information.... What are your water parameter? (ammonia, nitrite and nitrate) When and what are you feeding them? How often and how much water do you change? Have you noticed any of them being picked on by the fish or by other crays? When you found the dead crays, were the bodies dammaged? Have you added anything to the tank recently? Are you adding any salts or medications or have you recently?Good Luck!
 
just a friendly suggestion: Typing in all caps makes it really hard for people to read. Also, no punctuation makes it even harder. If you really want people to help you, they have to be able to understand what you are asking. As for your crays, the guppies shouldnt really be picking on them. I have mine in with guppies and have no issues. They are, however, VERY sensitive to high nitrates and require very clean water. Make sure you're changing a good amount of water at LEAST once a week depending on your tank's balance with plants, stocking, and filtration. It is also really easy to overfeed these guys. They are scavengers and will eat uneaten fish food as well as anything you give them. If you overfeed the tank, your water can foul very quickly and that can really impact them. Clean water is a must and if you dont have the time or inclination to keep it pristine, you shouldnt have these guys.Another mistake that people make is not giving them enough places to hide. Especially after they molt, they are vulnerable to injury, stress deaths, and infection. If they dont have a place to feel secure, they wont last very long. Also, unlike shrimp, they require hard water. A calcium supplement is also good to have. Make sure you leave the molts in with them; they will eat it to regain minerals to help strengthen their new exoskeleton.
 
Get a test kit for pH, GH, and KH. It will tell you what your water is naturally. Messing with hardness also changes your pH, so you have to be careful about your plants and fish before you do that. Adding some crushed coral can raise hardness, but you want to check what your water is first. In general, a higher pH will mean harder water, but not always, which is why its important to test for both. Once you have the readings, let us know and we can tell you if its ok for your crays.
 
Hello everyone. I did a ph test and the results were a 7.6. I also did an ammonia nh3/nh4 test and the result was 0 ppm.
I'm not sure what the cause of the CPO crayfish dying could be? how do u test for copper? could it possibly be that I'm over feeding them? when doing a water change, do I need to remove the fish/crayfish from the tank?
 
You can buy test kits for copper. I'm worried about your test results. Did you use a liquid test kit? The strips generally arent very reliable. To have 0's for all of your nitrogen tests is a bit fishy. Usually a cycled tank, unless it is very heavily planted, will have at least some nitrates. Your pH is fine. Did you buy a kit to test for GH and KH?

As for water changes, are you vacuuming the gravel? If not, that could be a problem. Since crays spend most of their time on the substrate, if a lot of waste builds up, there could actually be much higher levels than the water you're testing due to the waste building up in the space between the stones. Sand doesnt have this problem generally as long as it is stirred. You should not remove the fish when and crays when you do a water change, that makes it even more stressful for them. Also, make sure you are using dechlor since the chlorines and chloramines in tap water can kill fish, inverts, and beneficial bacteria.
