Please could someone help. My black Molly seems to be suffering, from what I am not sure. She does seem to have a "V" shaped tummy but no fry as of yet. So I'm not sure if she's pregnant or not. She is trying to separate herself from the rest of the tank, hiding behind plants or the filter. She is popping LOADS and is staying very still most of the time and "panting" She's been doing this for about 3days..
