Guppies have Popeyes. What should I do?

[guppycory]

I have 5 guppies (2 males, 3 females) and 3 cory cats in 20g tank. A week after i put guppies in the tank, i found 2 female guppies had a popeye on only one eye each. What should i do?

Well treatment is easy, daily water changes of 50% with the addition of Epsom salt to draw out the fluid behind the eye. Add 1 tablespoon of salt for every 5 gallons, then replace the Epsom salt you removed during the water change.

Next the cause should be addressed, this can be a bacterial infection, injury, or signs of poor water quality. Since you have multiple fish I'm guess water quality. Do you know the actual water conditions? Was the tank properly cycled?
