im freaked out!! another rasbora dead...HELP

[Meredith]

I lost a rasbora. Went to feed the fish this morning and one of my baby rasboras was dead!! It really frustrates me when a fish dies for no apparent reason. I am setting up my hospital tank tonight. I want to get my cory outta there (he is having a fin problem) just incase there are some bad germies floating around.

How old was the rasbora? What are your water parameters?

 

[Cherry Barb]

The water parameters are most important. And...How long has your tank been set up? And have you added any fish recently?

yesterday when one of them died I thought, oh well, it was a new one so maybe it was already sick or something. this morning one of my older rasboras was dead. I am pulling my hair out! My water tests fine, no ammo no nitrites, nitrates between 20 and 40ppm. I am doing a 30% water change(as we speak), vac'd the gravel a bit. I see NO signs of illness other than my cory whos fins are in bad shape, but it doesn't seem to be bacterial. The only other thing I can think of is the new angel fish. Could it have carried something from the store to make my other fishies sick? Do I just keep doing water changes? I dont want to start dumping in meds but what if all my fish die?? what do I dooooooo? Oh oh, I know people will ask, my tank has been up and running with fish for about a month and a half.

Looking at them now, one of the rasboras looks sorta washed out. the black isn't as black as the others. I would post pics but its not something you could see with the camera I have. Its pretty subtle. I cant tell if it may be covered in a whitish film or if the color is faded away. My husband remarked that one that died before looked like its color was faded. a symptom of something?

These fish were probably ill before you broght them home. Did you QT them before introducing them to the tank?

I am going to merge the two threads to keep everything together.

 

[Meredith]

It could be that one of them was ill, but they have been in the tank for about 2 weeks. Why would they suddenly be dropping dead?

 

[Menagerie]

That may have been the disease's incubation time. Most people will recommend QT for 2-4 weeks before adding to the main tank.
You need to remove those rasboras ASAP.

I have a hospital tank set up. I was going to use it for my corys damaged fins, I bought some melafix for him. do you think I could put them all in together?
