FF, I think you know quite well 4 days is literally nothing, especially since he came healthy and well fed (unless that's a bloat or a clog). We are not talking a baby aro at 1.5". When it will have been 4 weeks, then I'd worry just a bit.

If your NO3 is high, fix it and have patience again :)
alright, cleaned the filter and did an 80% water change. And, just because I am curious, could it REALLY make it 4 weeks without food? also, I never really thought of it but is it normal for these cats to just sit around... mine does all day then in in the morning (today) it swam all around for an hour...
 
Yes a healthy larger catfish can go 4 weeks PLUS without food. I have an Oxydoras that's going on 5 weeks right now and doesn't look like he's lost an ounce of weight.
 
An 80% water change is too large. You really should never go over 50%. It can cause shock from a big water chemistry swing. In the future maybe do 50% 2 days in a row. I have done 4 25% changes in a day due to an emergency. Nitrates aren't that big of a deal usually. How high was it?

It has happened to a dozen or so of my cats. 2-3 months - almost has no effect. 4-5 months - they get thin. 5-6 months - close to emaciated. Starting with a healthy fish.

The more space it has, the more it will swim (when it is totally adjusted).
 
Just my two cents on the whole activity question that you brought up. I have an RTC at home that is around 6". You must realize these fish are nocturnal. I can leave the light on all day and at times the fish stays in the exact spot all day. Once the light on the tank goes out (not even in the room) the fish begins searching the tank. Take a look at your tank in the middle of the night you'd be surprised. Also, I work at an aquaculture sport fishing center and we have a large RTC in an indoor pond setup. With size (and comfort in tank) these fish get active. All day the large RTC can be seen swimming and searching for food.

i always leave the light out... mine was REALLY active this morning but not eating...
 
Try a pellet food or cut up small pieces of worms. Blood worms shrimp. Keep trying different things but remove all wasted food
