Discus staying in corner and one at an angle.

[rdub]

Had a discus that was injured. Appeard to "grow" fungus around the injury. Wasn't able to remove injured fish til yesterday. It died today. Question that may be related to the injured/dead discus. After the injury the fish developed what looked like, maybe, fungus around the wound. I now have a "film" on the inside of my tank with the other 5 discus. All were very healthy a couple of days ago and now these are staying in one corner. I did about a 30% water change today. Anything you can think of that might cause the film on the inside of the tank and bothering the remaining fish?

As I recall all 5 fish looked good this morning.

Treatment?

could be slime coating?? I would be doing more than a 30% change. Keep up with big regular water changes with a wipedown of the glass and see how you go.
what are your ammonia nitrate and nitrite readings. Sounds like it could be a water quality issue

Wipe it down with what, just paper towels or?

[lpiasente]

Yep good old paper towel. You can use magents or an aquarium cleaner but I use paper towel.

Two things can cause this film

1) biological filter not working which will result in ammonia and nitrite

2) bacterial infection.

We can rule out the first with a simple water test.

If it's bacterial you will need to treat

IME wounds will only fungus if the water quality is poor.

What size tank? Filtration? Maintenance, etc?

[rdub]

60 gallon tank. PH 7.5. Hardness 100 ppm. Temp about 84. No new fish. All happened when fish was injured during fight to protect eggs. Remaining 5 looked fine yesterday morning.
