Hi Paul,

thank you, but as this is a fixed focal length lens it is not really what I'm looking for.

Hi,

please do not use Brita-filters for tank water. It contains silver which may dissolve.

You can use a full desalter(?) or demineralized water.

Depending on your current GH I would prevent to do a huge water change as it will also be stress for the shrimp. I would so it step by step... I'm not sure if it is the same with fish and shrimp.

Hi Mustafa, OK - lets divide :wink: There are the real dwarf shrimp (Caridina/Neocaridina) and the small sized shrimp... I'm looking for the last one. :roll: What I currently found is Peru zebra shrimp Euryrhynchus amazoniensis which is - with 3cm - small sized. http://www.aquarium-glaser.de/maxtool...
