Betta Has Pop-eye

[Kelsyann]

I noticed yesterday that one of my female Bettas wasn't looking too good. I immediately tested my water and my stats were:
Ammonia .5
NitrIte 0
NitrAte 10
pH 7.6

I was shocked to find the ammonia so high so I immediately did a 50% water change. I don't know what caused the Ammonia spike, my tank has been established since March, and I haven't added any new fish in over a month. Today my water stats are
Ammonia .25
NitrIte 0
NitrAte 0
pH 7.6

I'm going to do another water change in a few minutes, but anyway, back to the sick Betta. Her left eye is very swollen and has taken a kind of reddish color. She wont eat and has just been hanging around by the filter. I thought she was dead this morning but when I went after her with a net, she darted away. I have since isolated her to a 2 gallon bowl and I'm doing water changes twice a day. I don't, however, know what medication to give her for her eye. Anything would be helpful. I live in US, so no UK based meds please.

Find a good general anti-bacterial medication and use that until you can ID what exactly is wrong with her. I would suggest the one I use, but you probably can't get that in the US.

My female betta recently was cured for this i treated with myaxzin, its brilliant stuff and worked like a charm seen as your in the u.s i'd prder it from say ebay or somewhere it will deliver to you.
Other wise i'd go with a anti bacterial med.

what size is the tank ?
tank mates?
temp?

When you get the anti bacterial treatment you need to be treating the main tank aswell just in case
popeye is sometimes caused by stress aswell as water quality

Is there any sharp ornaments/plastic plants in the tank she could have injured herself on

when did you last do a gravel vac

I would do another 50% water change - via gravel vac - and also rinse the filter media in the tank water you take out of the tank - incase the filter is blocked in anyway

what sort of filter is it ?

 

[Kelsyann]

the tank is 29 gallons with 2 Tetra 20i Whisper filters, so I have enough filtration technically for 40 gallons
tank mates:
9xfemale bettas (including her)
6xNeon Tetras
4xPanda Cories
1x BN pleco

Temp= 78-80* F
I don't think there are any sharp pieces, I have all live plants, 2 pieces of bog wood, a coconut cave and 2 whole terra cotta pots.

I have sand substrate, but I suck all the gunk off the op every time I do a water change, so last night would have been the last time I gravel vaced.
