sick seprae tetra with bulging eye

[jl8013]

Today, I just noticed that one of my seprae tetra got one bulging eye. This fish has been swimming by itself for a few days now. I had total of six tetras in a 29gal tank. I'm going to change the water tomorrow. Is there anything I do for my sick tetra? :( I also noticed that the tip of its top fin is white, and it always swimming at the top half of the tank, while other fishes are swimming on the bottom.

Bacterial infection most likely. If you want to save it you need to get it into another tank, and treat with a antibiotic. Maracyn and or Maracyn II would work. Don't expect him to make it however, when the infections are that severe its not a very good recovery rate.

can someone please tell me why my black fin shark is dying? He was fine and then I found him in some foliage, I got him out of the foliage and he swam around for a moment but he is just being pushed around by the bubbles and the filter. He is still breathing but barely, I tested the water and it is fine and the temp is fine, what could be wrong?

maybe he has a swim bladder problem since yopu found him stuck in the foilage. Or he could also have some kind of infection bacterial or fungal, cannot really tell unless there is some other sign of distress.
