    I wasvery sucessful breeding CRSs with slightly high Ph, somewhere around 7.2. I was told to keep the Ph in about 6.5 to 6.8 but it never turned out fine, breeding wise. Some of the brazillian breeders also report the same situation concerning the water Ph.

    I just remembered something. About 2 months ago, I replaced the substrate and now I'm using one that is artificially colored, in black. It didnt change any of the parameters I'm able to check, however since that, all of my CRSs stopped breeding. Could that be the cause?
    It could be due to the subtrate... I've read that artificially coloured subtrates will leak toxins into the water... Which could explain why your CRS are trying to climb out of your tank & stopped breeding as well...

    The only thing I can suggest is to remove all the subtrate... I know it sounds drastic but I feel it's the best solution to your problem...

    My colleague manages to breed CRS like rabbits at PH 7.5 using artificial black quartz sand.

    Black Quartz... the same thing I use as substrate. So perhaps its not the substrate thats giving me a hard time with the shrimps.

    A few days ago I moved the tank to another place, to avoid the smoke in my room, because I smoke. It seems that the shrimps are not trying to escape anymore... at least not as before.

    Well... I'll wait afew more days to see what happens.

    Shoud I keep more hiding spots for them? In my tank there is almost none.

    hi... same thing happen to me but on cherry.

    Anyway, not sure if this is the cure. I introduced new batch of cherry shrimps and mix with the existing one. Few days later, they start getting 'pregnant'.

    Let us know the results.... if it works, maybe there's a reason why.

    Good one...

    I've heard that it could happen if we stick too much on breeding with the same shrimps all the time. Maybe I'll try to get new shrimps to increase gene variety among them.

    ThanX

    Hi, Actually, i have some probelm also but...this looks somewhat different.

    CRS stop breeding when there is not enough room. 40CRS in 40liter tank and not enough hiding place could be the cause. The number of the CRS reached the saturation point.

    CRS can breed in pH range up to 7.6.
    But, I perfer those high grade CRS, 6.0-7.2 is best in my option.
    I don't think pH doesn't effect much.
    How much water change do you do in 1 month?
    Do you clean your filter?
    Do you give liquid on your tank?
    Think what you put in your tank as time passes.
    Also, check your temperture offten. If temperture chagnes up and down too much, they might not breed.

    Yes. Don't put too much shrimps in one tank. They do poop a lot and when you give food, they fight for it.
    I would get another tank if you have too much.
