Black Molly sick?

[sparker24]

So I just noticed that my black Molly's eye looks swollen shut. Any ideas on what it might be from and thoughts on how to cure it?

Sorry forgot some other details

The parameters as of two days ago were good.
Ph = 7.5
Ammonia = 0
Nitrate2 = 0
Nitrate3 = 0


The tank is 45 gallons. It has been setup for around two months.


I am running a Aqua-Tech 40


There are 16 fish in the tank (moving some to another tank soon).
4 X mollies
4 X guppies
1 X guarami
4 X hatchet fish
3 X sucker fish


I did a vacuum change a week and a half ago and was getting ready to do another when I noticed the Molly. I vacuum the gravel and do a water change (25-30% each time).


I have had this particular Molly for about three weeks now. I introduced by floating the bag and pouring in tank water over an hour or so.




I have been feeding my fish tropical flakes in the morning, and switching back and forth between freshwater flakes and blood worms at night.

Is it swollen or just foggy? Maybe she is just blind in one eye
