It Died! :(

[Sea Wraith]

I think you hit the nail on the head! In the LFS store where I get my water his lines are all copper. He has his lines hooked up to a RO/DI and water purifier system but I take it the copper could still affect the water! Even though the test kits showed no copper is this possible? This very well may be the reason that my ceph died! I also never put the LFS water in my tank. I do float the bag in my tank for 20 minutes then start adding a few ounces of water from my tank every 15 minutes for an hour and a half to acclimate the fish. :sad1:

Your water may not have any copper since you were careful not to add any LFS water, but what about the day or days the octopus was sitting in the LFS's tank? He could have gotten a copper overdose there?

Copper usually takes a few days to do in an invertebrate. After exposure, octopus and stomatopods will eat for a short time, but eventually they die. I recently had a supplier ship me a collection of octopus and stomatopods that were mistakenly placed in copper treated water that he used to treat fish. I was not as careful as I should have been and contaminated three 125 gal tanks. I eventually had to dump all three set-ups.

I noticed one other thing reading this thread. It was mentioned that the salinity was "24". I suspect that this referred to a specific gravity of 1.024, about what you would want for water at 23 C, but many aquarist also use refractometers where you want about 34 parts per thousand. I have seen people confuse the desired "24" and "34" and end up placing animals in water that was hyposaline. It is probably a good idea to get into the habit of specifying which measure you are using. I know this is old hat for most people on this board, but...

I am really sorry about the loss of your little octopi. I know how it feels, I just lost a Chambered Nautilus.
