well i think there is something killing my inhabitants.. i had a blue tang that died yesterday, and today i woke up and one of my clowns were dead. ph is 8.3 ammonia is 0 nitrites are 0.1 and nitrates are 10. i dont know what could have happened to my clownfish because i cant even find his body (maybe my hermits took care of that) so any ideas of what could be killing my fish?? other things i have in the tank are: 3 peppermint shrimps, snails, hermits, cleaner shrimp, yasha goby, candy stripe pistol shrimp and a blue coral banded shrimp. so any ideas anyone? thank you
