One of my female guppies died last night for no apparent reason. Can a fish die from complications due to pregnancy? It would either be that or an internal infection i couldnt notice. I suspected she was preg b/c she was steadily getting fatter and more aggressive. But she was still active until I turned off the light for the night. This morning she was dead. I checked the water earlier that day(yesterday) and everything was perfect. And all my other fish are active and full colored. Any thoughts?
Thanks for your thoughts
