I have an oscar around 7 inches long in a 75 gallon tank all to itself and it has been doing great up until about 3 days ago when I came home from work to find it just laying in the bottom of the tank in the corner. Its gone from eating everything in sight like a normal oscar to not eating at all. Its color looks good and normal(not pale at all) gill functions seem normal and it shows no signs of any external problems that I can see. From looking at it,it looks healthy. But it continues just to lay in the bottom of the tank(not on its side) or in a cave showing no real signs of swimmming and beginning active and as I said before hasn't eaten in about 3 days. Any advice or help anyone can give me on what I need to do will be greatly appreciated. Thanks in advance.

Can you check your nitrate levels? I like to see them at between 10 & 20. Have you got lots or water movement in the tank? How often are you doing water changes?

Before you criticize someone walk a mile in their shoes. That way you're a mile away and you have their shoes.

Sorry did not realize I had forgotten to post nitrite and nitrate levels. Nitrite-0 ppm Nitrate-10 ppm
I have 2 100 gallon penguin bio-wheel filters and 2 air stones 1 on each end of the tank. I do a 20% water change once a month.

Things have taken a turn for the worse as of this morning. Oscar now laying on side with fins clamped to side. Gill function very heavy.

Could something have gotten in the tank like a chemical?

I can not say that I'm 100% positive nothing got in the tank,but the chance of it happening are very very remote. The tank sits rather high up and is basically completely covered.

Hi,
Any idea how old this fish really is? It could be
succumbing to old age. Has it always been kept by itself
or is this something that just happened. Sometimes they
need distractions in the tank to keep them active and going.
New rocks in the tank? An undergravel filter along with
the others?

Woke this morning to find my oscar had passed away sometime during the night. With the help of my 5 yr old daughter we placed it in a box and buried it under a pine tree in the backyard.

So sorry for your loss. I'm sure it was old age that took him, you can always try again with a baby or two... that way you'll have a longer time with them!
