Moving shrimp

No they are dying their still reddish in color if they were molting then if would be clear and my numbers are diminished to possibly 15-20

So refresh my memory, you moved them from a larger to smaller tank?

 

[giffmastaflex]

Yes I moved about half the water too and the same filter and some of the rocks really the only difference between the two tanks is a different sand and a smaller tank

 

[Brookster123]

What kind of sand?

 

[giffmastaflex]

It use to be play sand in the 20 but now it's pool filter sand

I don't know here, if your water parameters are good than I'd look into some kind if contamination, or really reaching.. Do shrimp fight over territory? The smaller quarters could causing issues???

 

[giffmastaflex]

Not that I know, the only thing I could think of is stress

It could be that the substrate holds a great deal of BB.

After thinking about it, in regards to my situation, where something similar happened, my opinion is that it was the loss of the biofilm, and bb from sand/substrate, causing a poor environment. I know I did water changes less frequently and maintained the same schedule, although I had less bb to process everything the same as before the tank change. I didn't take into consideration that little info. and I wasn't testing the water because I had been on auto pilot so long, I didn't "need" to.

Also I would check your kh/gh and tds.

Sometimes it is a molting problem. Not enough nutrients and or calcium.
