Just curious, but you seem to have been making a lot of threads on a lot of big fish? Red tail catfish, pangasius catfish, clown knife, and paroon sharks?
I can't help but wonder, do you have several tanks or ponds of tens to hundreds of thousands or even millions of liters to put them in? Especially this species, which will grow to 3m long and is extremely active as well!

As for the topic of the thread, in addition to checking the water and fixing it if it has any problems that need to be fixed, keep in mind this species is very high strung and easily stressable.
I'd also look into decorating the tank with substrate, fake plants, etc. The bare, unnatural environment is probably stressing it out even further.

I don't see any scars or swelling on the photo.

If it acts stressed, may be the switch between the tanks was stressful, or the water between the tanks is significantly different, or your water is not cycled, or it is simply not right for this species, or maybe it is bullied, or stressed by too much light, or too much motion around the tank, or not enough DO, etc.

If you'd like a more or less complete troubleshooting guide to fish appetite and health issues, here is one I put together. It may give you ideas what to look at.

Also, a lot of this info is usually needed for any worthwhile attempt to help you troubleshoot your situation. The less we know on this list, the less helpful we are. For example with the info in your OP, we pretty much can be 0% helpful.

If I recall correctly, you don't measure your water for ammonia and nitrite, which cuts a LOT of ground from under any attempt to help you.

Water Parameters



by a liquid test tube kit, such as the API freshwater master kit:

-- ammonia, ppm

-- nitrite, ppm

-- nitrate, ppm (before and after water change)

-- pH of tank and tap (before and after water change)

-- is the pH steady?



-- dissolved oxygen (DO) or description of aeration and stirring



-- temperature

-- is the temperature steady? (no significant swings?)



-- carbonate and general hardness, KH and GH, by a liquid test

-- TDS, ppm

-- or a general indication of TDS or water hardness and salinity



Water Source and Water Change



-- municipal or private

-- disinfected by chlorine / chloramine or non-disinfected?

-- if disinfected, how is water conditioned before water change?

-- average water changes (WC) on tank:

how much

how often



Tank



-- size

-- length, width, and height

-- time of running

-- if the tank is new:

how long was the tank cycled?

how was it cycled?



Stock (all fish, not just sick ones)



-- what species

-- how many each

-- estimated size of each

-- how long fish in question have been in tank

-- how long tank mates have been in tank

-- tank mate interactions, any aggression?

-- wild caught (wc) or captive bred (cb)

-- dewormed or not

-- treated against other parasites or not



Filtration



-- type: canister, HOB, or sump?

-- size

-- pump flow, gallons or liters per hour?

-- how often cleaned

-- how cleaned



Diet



-- what is the fish fed?

-- how much

-- how often

-- what are the tank mates fed?



Disease Symptoms, etc.



appetite

lethargic

bloated

swimming pattern

spots (where on body)

fuzzy patches (where on body)

excess slime

distorted features

color change

cloudy or swollen eyes

prior health history

-- of fish

-- of tank mates

were fish quarantined before being added to tank?

did the tank experience any previous disease out breaks?

-- what were they?

-- when were they?

medications used



Photos



-- the entire tank

-- close-ups of the fish and problem areas

What are the dimensions of that pond? It looks rather narrow, which worries me in terms of possibly not providing enough turning space.
Thanks for showing me.

Did you get a chance to decorate the paroon shark's tank, by the way?
