Hi,
Last saturday I got a group of 10 julii cories, and over the past week I've gotten 3 deaths. My parameters are 0 ammonia, 0 nitrites and 5ppm nitrates.
The rest of the fish look fine, my angels, platies and bn pleco are fine.
Is this just a case of new fish dying or should I be worried? I treated the cories with meds when I first got them too.
