Hi everyone, please help me! My motoro female stingray stopped eating two days ago. I have put mysis shrimp and nightcrawlers right in front of her and she is just ignoring them. I did water tests and discovered my ammonia was at 4.0, so i did a 25% water change. The temperature in the tank is 84 degrees. I know that they are best kept between 76 and 86 degrees. Is it possible that the water is too warm for her? My humerosa is in the same tank and he is just fine. I have had her for over 6 months, and I don't recall her ever acting like this before. Please help! Thanks!
