thanks for your quick replys
i have read that the ideal tempreature for cherry red shrimp is 27 celcius, for a while the tank was at 30 celcius and they where fine, i did not have a digital thermometer and my fluval edge heater must have been faulty, since then i have used an adjustable heater and set it using a digital thermometer it not stays between 26-27 celcius.
would you sudjest colling it down to arroud 22-24 celcius to see if that make a difference?
no i have never seen a berried shrimp in my tank.
i think my problem may lie in my male to female ratio. is there a given amount to aim for or should breeding be possible with one of each. i'd have thaught the bigger the population the better withing reason
also i have trouble telling the males and females apart. i know the females are bigger especialy at the rear but i see larger ones with the rounded under bellies with no saddle and smaller thinner ones with a saddle. also some of the saddles are dark almost black in colour.
a few weeks ago i noticed two of my shrimp with a thin clear band around them one thinker than the other's, i read that this was a resuls of stress but i could not think of anything i had done to cause this, niether shrimp has died and one has no clear band at all now the other still has a slight one left. any ideas what may have caused this.
as for my water perameters i dont know much other than every time i have the water tested at the lfs it is all fine 'perfect' is what the tester says most times.
i will have the tests done tomorrow and record the exact levels if this helps
again thanks for your replies and any more info or light you can shed on the subject would be great
