My female Guppy gave birth a week ago. She was fine for a few days but is suddenly swimming tail down. Whats wrong? What can I do?! My water parameters are good. I did have issues with temprature fluctuations for 4 days but was watching it like a hawk and have it stable now. I am thinking its either due to temprature fluctuations, male being over agressive, or the algae wafers for the cory? I wont rule out possible bacteria/parasite issue.
Swim bladder disease? Do I wait and see if low stress helps? I have removed the aggressive male. Do I salt? Do I medicate?
