    I have been attempting to keep red cherry shrimp in a very established 10 gallon planted tank for 2.5 months now.
    However, the shrimp are slowly dying off 1 or 2 at a time every couple days or so.
    There are only the RCS in the tank with a sponge filter, so no predators.
    I have tested for PH swings at night and have found this not to be the case.

    WATER PARAMETERS:

    TANK - 10 Gallon (cycled / Established)
    SPECIES - RCS adults x5, RCS newborn x35
    ACCLIMATION - 2 hour slow drip from air bubble reverse draining with adjusting knob.
    PLANT - Heavily Planted
    FILTRATION - Sponge Filter
    TEMPERATURE - 78 Degrees
    AMMONIA - 0
    NITRITE - 0
    NITRATE - 0+
    GH - 16+
    KH - 5+
    COPPER - 0
    MAINTENANCE: 15% Water changes twice weekly.
    Food: - Blanched Veggies, and Omega One Algae Pellets.


    I started with 10 beautiful Blue Velvets who seemed estatic to be in their new home.
    They were zooming all over the place foraging and very aggressive eaters.
    After becoming familiar with their new home 2 days later they began to calm down a bit.
    On day 4-5 I noticed the first dead BVS.
    They continued to die in this manner until they all were gone roughly 3 weeks or so later.

    Im persistant so I was not deterred. I bought 20 Fire Red RCS in which I bought locally.
    TLDR: The same thing happend to the RCS that happend to the BVS.
    Although this time they did manage to have a couple clutches of young.
    I have had the RCS for roughly 2.5 weeks now and have noticed that only the adults are dying,
    but I dont believe them to be dying from old age, but another cause.

    CONCLUSION: I believe the shrimp are dying from constriction.
    I have also witnessed shells that seem *too small* for the shrimp.
    These same shrimp seem to die a day or so later.
    I really don't have the time for the added hassle of an RO/DI unit, or Peat water changes.
    I really enjoy using my 25 Foot Python.

    QUESTION: I bow to the shrimp experts and plead for your advice.
    Would lowering my temp from 78 to 75 help slow the shrimp growth enough to prevent the moulting deaths?
    75 would be as cool as I can get due to not having a chiller or the ability to use a fan on an open top (Rampant 2 y/o son).
    What else could I do to prevent these deaths?

    ADDITIONAL INFO: In the 2 - 3 weeks that i've owned the RCS I have only found roughly about 3 or so molts.

    Switch on the lights at night, look for flatworms on the glass. RCS are usually bulletproof. Added any new plants within recent weeks? Some plant imports are treated with insecticides, that also has a bad effect on anything with a chitinous exoskeleton. Only needs small amounts. I know you say that it’s only the original adults that are dying and so this doesn’t fit, just trying to eliminate a few obvious shrimp issues.
    We have RCS here at temperatures between 70-82F without issue, I’ve housed them outside over a UK Summer when average temperatures were probably around 65F without issue, hard water, soft water, clear water, green water.

    Thanks for the advice, and holy cow out of all the research i’ve done i’ve never ran across anything about flatworms!! Good thinking!!

    And to answer your question, yes. I’m almost always adding new plants. Small tweaks here and there. It’s such an addiction, but its good news that you have had success with such a wide range of elements.
