Tetra's Eye Red And Puffy

[ShinyCard255]

So I came home from work and my poor Tetra's eye is red and twice the size of his other one. I have no clue what this is or how this could have happened.

Other fish in the tank:
5 X-Ray Tetras
1 Glowfish
1 African Dwarf Frog
1 Black Mystery Snail

I did just put a new piece of driftwood in there within the past week along with some Java Moss.

Any help would be awesome!

Did some quick research and could it possibly be pop-eye?

Water parims?
Tank size?
Also Glofish are shoaling fish and like to be in bigger groups. something to think about when everything in the tank is better.

0 ammonia, 0 nitrite, 20 nitrate
its a 15G

It looks like pop-eye to me. The tetra was taken out and put into a hospital tank and am treating him with epsom salt at the moment. I also did a 50% water change on my 15G once I moved him.

Yes I know the Glowfish should be in shoals, but my wife wouldn't shut up about the fish in the LFS so I had to buy it for her...
