Neon Tetra Died, Other Fish in Aquarium in Danger

[whsthatlady]

I have had four neon tetras for almost a year now and one died yesterday after it developed a black coloration between its dorsal fin and its eyes. The coloration developed for a week or two and then I noticed it starting to list aimlessly and shimmy a little back and forth. It died the next morning. The other three appear to be normal. I also have an albino cory catfish, a Plecostomus catfish, and four fancy tail guppies in the tank as well. It is a ten-gallon set-up with a heater and a Tetra Whisper Filtration system. I am worried about the other fish in the tank since the one Tetra that turned black died. I have researched fish diseases on the web and have not come up with anything. Can anyone help me or suggest anything so that I do not lose my other fish?

well your first problem is neons can not survive saltwater :?

I assume by your fish list that you meant to put this in the FW side and not the SW side so I'll move it.

Did you test your water parameters? I can't really say for sure what the problem might have been. All I can suggest is do weekly water changes and keep a close eye on the other fish. If any of the same symptoms arise, then I'd worry.
