New fish fail

[Stacemira]

After much troubleshooting, we were able to determine that my 25 G was fully cycled and now ready to add fish.

I went to the lfs, and purchased 7 barbs for the tank. 3 days later one of the greens had pop-eye. Then the next day another one had it. Chems were couldn't have been more perfect. I have now taken all of them back to the store and I did a 50% water change.

Question to you is, now there is no more fish in the tank, and with the water change, will it be safe to put new healthy fish? Or should I be treating the tank?

Depends on the cause of the pop-eye. Where do you think the pop-eye came from?

Maybe the popeye came from a live plant? Not sure if that can happen or not. You should probably disinfect everything somehow. I think I heard of using bleach (on plants), but I'm not at all sure about that being a good idea or if I heard right.

Pop-eye is a symptom of an internal infection that's causing fluid to leak into the eye. (Ew.) Clean water and epsom salt is a recommended treatment, but the fish should be moved to a hospital tank for the duration. There's a good article on it here:
