Juvenile 8" super red Arowana very stressed and not eating food for over a month.

[psylent_darkness]

It's been over a month since I bought this fellow home and I haven't seen him playful and happy. He is very scared, stressed and swims erratically when we go near the tank.

He hasn't eaten well at all. Initially I saw him eating live shrimp but now he barely eats anything and it's very concerning because it's been more than a month since I got him home and I'm so worried about his health and life from here on.

Kindly advice what I should do to build his trust and make him aware that I'm no harm. I have had 3 arowanas in the past and my most recent one died after spending 15 years with us. This one is very different from the rest and I'm concerned about it's well being.


Kindly help me with the best approach to make him trust.

Questions?
Tank size, Length x Width.
Temp, pH and other water parameters.

Is he not eating at all?
Or is he just eating sparingly and at intervals?
Every few days, once a week or what?
What has he eaten?

Filtration outflow, is generated current heavy, moderate or low?
Low or moderate, best.
Even high outflow filtration can be diffused by splitting and direction.

Things I'd try,
Dimmed lighting.

Dark background and at least one end of tank.

Floating plants, and/or a section of tall plants, or branch(es) forming a screen / area to hide.
A section of clear tubing with suction cups on both ends keeps floating vegetation at one end of the tank.

Plant a chair/recliner near him, then just sit and kill time.
Become as omnipresent as the hum of the filtration.

Time...
