60 gallon tank
all levels are perfect
2 oscars
3 plecos
1 catfish

At fist i thought that they were just getting into little fights but now i think one of the oscars has something more. The first picture is the oscar that is acting fine, the second one is the fish i am worried about. I just put in in his own tank because he was eating less due to being "picked on" by the healthy oscar.

Any ideas will be helpful. Thanks in advance, Mike

Okay, how big are the fish? Unfortunately you have far too many fish for your size tank, it's only big enough for one Oscar. Also, the photos are too small, I can't see enough detail. Finally, can you please give us the exact water results, i.e. ammonia, nitrite, nitrates and pH?

i clicked the pics and they show big.
Something is off allright.

the pictures showed big and Mozilla Firefox, so that's crappy old Internet Explorer for you. Anyway, I can't believe that a fish would end up looking like this if the water quality is good. Somethings not right somewhere, we need to know those water results. It looks like a fairly young fish as well, maybe five or 6 inches

Just a thought, does the skin looks slimy at all?

nitrate-50
nitrite-.2
hardness-75
kh-100
ph-7
ammonia-.15

as far as a slimy look.. it dosent seem to like like that. And yes they are about 5 inches both.

tanks too small

How long has this tank been running? You water conditions are real bad.. You need to start doing 50% water changes soon and at least every other day untill they get better.. What filers are you running?

I'm sure you'll get more solutions soon.. Good luck with your fish

Your tank isnt cycled, so either it hasnt been running long, your filter isnt working properly, you dont have enough filtration or you have been cleaning your filter in tap water.

How long has your tank been running, is your filter working, what filtration have and how do you clean your filter

Your fish with problems could be becuase your tank isnt cycled or fighting or both.

Please read the section on the site on cycling

You need to do a 50% water change and then 25% everyday until you get test results of ammonia and nitrite of zero and nitrate less than 40. Then test weekly, if nitrate above 40 then you will need to do bigger or more frequent water change

Your tank is only big enough for 1 full size oscar

if you can not put things in proper places...i am afraid you will lost them all.
as delboy suggested, do large water change immediately without cleaning the
filtration system.

Will do guys, thanks for all the help. Ill keep you updated.
