Cloudy eye betta sorority

So my betta sorority came in (there’s 5 girls) and I started them off in a 10 gallon to see how they react to eachother and to monitor for illness or anything before putting them in the 20 gal. Recently however I’ve noticed two of them have cloudy eye. I have everything to treat and test the water. The only thing I don’t know is if I should go ahead and separate the other 3 that don’t have cloudy eye or just treat the all together?
Thank you

 

If you are able, I would separate the fish affected. Depending on what's causing it, you'll want to mitigate the spread as much as you can. If the other three come down with it as well, you could possibly put them back together, but you may want to just keep them separate depending on how you treat them, and how the treatment is going.

Treatment can be rough on any fish that aren't ill, if it's anything more than aquarium salts or general water treatments. If you're going to be using antibiotics or anti fungals, definitely separate!

Good luck with your bettas, I'm sure they will be very happy in that 20 gallon tank once they're able to move into it <3

Thank you for the advice! I’ve put the three healthy ones in the 20 gal so I can treat the other 2. I’m hoping it doesn’t cause future complications with the sorority but they’ve been together for awhile so I’m not too worried.

for some reason my phone makes the light seem pink but it’s a wire led. The grey one wouldn’t let me take a good picture but only 1 of her eyes is cloudy on closer inspection.
The 2 with cloudy eye:

 

I would do some research on diamond eye because that's almost what it looks like to me. It's a condition that is apparently common in dragon scales bettas. Might be something to look up further.

Thank you for the information! I looked more into it and diamond eye seems to be far more likely the cause. 3 of the 5 have it now and if it’s a genetic problem it makes sense why they have it.
Additionally I’ve been treating for cloudy eye and nothing seems to have been changed. So far they don’t have much issue eating and they seem know when it’s time to eat.
