Shrimp Acting Weird

[Dizzie]

yesterday I introduced some new plants, a few new guppies and a co2 system

The missus (in her infinite wisdom) decided to do a 50% water change just to throw things into the mix and now the day after all my shrimp are lay on their sides waving their legs/arms/limps around. 1 or 2 are swimming, but nothing like before. I also gave the plants their weekly dose of food since they were dying like crazy before I started doing that.

any ideas? it's a 100L tank with a fluval 2+ filter which was cleaned in the water we took out. kept at 24 degrees, but I can't tell you PH or nitrate levels sorry. all the fish seem to be acting normal.

the new plants you put in there might have been given a copper treatment to rid them of snails, etc. if thats the case id assume thats why your shrimp are acting that way...they are particularly sensitive to copper.
all the best with them.
also check the ferts for high levels of copper (although most micro fert copper is in low levels)...jsut a secondary thought.

Ferts will be perfectly fine, but as said, plants will have been treated with copper in an attempt by the retailer to get rid of snails.

Add carbon to the filter and do another 50% water change.

Could also be adding too much CO2, but this is only going to be the case if your using a pressurised system, and the fish would be showing signs of it too.

So I'd say it's down to the plants.
