Well to be honest I haven't have much luck in these shrimp myself. don't know whether I should be blaming the water in stoke on trent of something that I'm doing wrong. There is too many variable in the equation.
Postulated theory of why my shrimp die
1. EI dosing.
2. Long distance travel prior to settling in my tank
3. Stoke water
4. Small tank
5. Bolbitis in the tank
I have managed to use RO water so I think no. 3 is corrected. Small tank probably won't get to change unless I get a bigger space and a bigger tank. 10g in my room don't do well as the temperature fluactuates between 21-25 degree everyday! There is also reports of shrimp keeper where shrimp had died mysteriously when they had place new rhizome plant in the tank and anubias seemed to be a no-no with CRS. Not sure if bolbitis is true. Travelling all the way accross half the globe doesn't help either. I would like to think that they will survive that travelling but unless I can get some quality shrimp from local source that is kept in the same parameter, I can't really comment on that. It is well known that even if the shrimp look healthy after delivery, they will die after 2 weeks or so in your tank if they weren't packed properly or the water quality wasn't ace when they were packing it.
I'm skinned from these shrimp at the moment. First time importing from taiwan cost me 250 quid and all died! So changes to RO water and made another order. Second order cost me 150 quid and still all died! The next batch ideally will be placed in a sterile 50 gallon tank with just RO water remineralised with Ca, Mg with no nitrate and no plants! That is if I can find any place to fit a 50gallon in my place.
