HRS>freshwater ends in massacre
Yep, it's pretty easy, just plop them into fresh water and they live. There's no need for acclimating them, at least in my experience.[/QUOTE]
Uh, no not for me this week. I had spent 2 mos. acclimating them from 1.005 sp (same as my brackish crab) and got it down to 1.002. I wanted to keep them in the container that I have a couple of newbie blue jellies in. I figured with the proper back and forth of adding water from each container into a separate container and then gently scooping them out with a plastic spoon all should go well. I kept their container up for 48 hours in case of emergency. They seemed fine, so I took it down. Colors were good. They were feeding, etc. They all died between the night of 48 hours to 72 hours. At first I thought maybe the two jellies had gone rogue, but no, I saw the last of the HRS die right in front of me. Good coloring, swimming around as I am removing dead shrimp parts and suddenly he is on the floor in a u-shape unable to move his back legs which quickly progressed to his front. It really saddened me as I had had my HRS for years.
I don't think you can move them down to freshwaterish and then put them in a different tank that is established and freshwater. Something was off, but it took several days to get them. I was leery of just moving them without acclimating them bc on some website somewhere, a guy in HI had bought some at a store not realizing they had been kept in brackish water there and he dropped them in his tank and they died in 24 hours.
Maybe mine were just too old to handle the adaptation. They could adapt to all kinds of brackish sp readings though...I would suggest someone lowering them to freshwater and then leaving them in that same tank and bringing the plants they want in to that tank, but since freshwater shrimp are so sensitive to salt, not more shrimp.
Maybe it was the almond leaf, although the container was still in the low 7's for pH....
I am going to be taking a break from them for a while. That was a bit of a shock.
