Bloodfin Tetra bugling eye
 

I transfered my bloodfin tetras to my new 36 gallon and they have been in there for a day. This morning when I went to feed them I noticed one of the has a bulging eye. It is bulgling out all the other fish are fine. It's just the ones eye that is wrong anyone know what this is?

It may be what is commonly termed pop-eye. An accumulation of fluid forces the eye out. I do not know if there are other causes.

I had a Congo Tetra with this a couple months back, and I removed him to a 10g QT and treated with kanamycin. To my knowledge this is not contagious (but i will accept correction if wrong) so isolating the fish in a QT is advisable as the water has to be treated.

I used Seachem's KanaPlex. It comes in a small tube and is a powder, and you add the measured amount (it has a measure spoon) three times at two-day intervals. It worked for me.
