Flashing guppy

[Zac]

Hey all,

I’ve noticed a couple of my female guppies are flashing and over the past couple days it seems to have gotten worse. Other than flashing they so no other symptoms of external parasites or gill flukes. They’re energetic, love to eat, etc. Tank conditions are normal. I have another male and female who aren’t flashing. Maybe it’s due to the guppy’s pregnancy because it’s stressful for them? I’m considering treating the tank with general cure just in case.

The fish have been in this tank for three weeks at a temp of 78 so I’d think any disease would have presented itself by now. Maybe they are sick?

Thoughts?

This is a reason some female guppies will flash. It can be an indication they are ready to give birth soon.
