Too many shrimp -- how to stop the population growth?

    Hi -- I'm new here . . . forgive me if this question has been asked and answered. I have a 60 gal. coldwater, freshwater tank, that is heavily planted. The goal is to have a relaxing scene, with schooling fish -- I have White Mountain Cloud minnows. I started with 5 red cherry shrimp, and I loved the tank's look.

    Then the RCS started to breed, I have too many, about 95 too many. I've removed the excess. Now the tank looks serene, again.

    My question: what can I do to discourage the RCS from breeding? Do I need to adjust the pH or some other water parameter to keep the shrimp from breeding so rapidly?

    Any help would be appreciated.
    Thanks

    Welcome to ASW can you fill in your Country as well as your location in your profile please.

    In my home town a local has them breeding like crazy in a pond outside and he sells them to the LFS.

    Most members keep their RCS in heated tanks.

    HI Miles,
    its a luxury problem having too many shrimps. Here are a few options:
    - you can sell or give excess away to friends or LFS
    - you can add some fish that will eat excess new born shrimp and keep the population stable
    - do nothing and the srimp will stop breeding like crazy by themselves once their number has become critical

    Only one small hungry shrimp eating fish would do the job for you.

    OK, but my goal is to have about 5 healthy, large, colorful shrimp always there. Can you suggest a fish that will just eat the small ones? I have a tank of Danios -- perhaps I should move one of them when the population surges, and remove it the next day?

    As long as you keep M&F in the same tank you will always have fry. The more plant cover you have the longer they will survive.
    If a shrimp looks like it can fit in a fish’s mouth, then the fish will probably eat it.

    This is an easily made shrimp trap, it might help you.
