Would check ur water to make sure it’s pristine but I suspect it maybe due to not settling in the tank. What was it feeding on prior?

Also the tank need to be upgraded at some point.

pump temp up to 30 slowly to push its metabolism and up for more water change. Put some feeders in there and let it settle

I've been using the same water with my other tank (120cm x 60cm x 60cm). in my other tank, I put Silver aro, Golden Aro, Jardini, also my snakehead. before I put my wolf fish in this tank, I've been using this tank (60cm tank) for my silver aro. the tank water is very clear. today I just come back from the store and asked the seller, he said he always feeding him with frozen shrimp. I tried but still nothing.

also, I forgot to mention that I give the wolf fish a hiding place like a pipe, bogwood, also plant, my wolf fish always stay in the pipe never come out.

Is this a newly setup tank? has it been cycled? What are you parameters currently?
nope...before I put my wolf fish in this tank, I used to put my silver aro for 5 months in this tank without any problem after that my wolf fish came and i moved my silver aro to my 300L tank and i put my wolf fish in 55L tank.
PH 7...Temp 29C

I got ya fist questions I would ask anyone having fish problems. When I was asking about parameters I was referring to ammonia nitrite nitrate. If everything checkes out I would start worrying about internal parasites and start thinking about putting the fish through a medicated quarantine period.

Last night I pump up the temp to 29C and put a pinkie and a small crayfish and turn off the light. in the morning I wake up all gone. so my wolf finally eat. but is it ok to my wolffish to never come out from the hiding place and always scared of light? in the store where I buy it, the wolffish always come out even they give them a hiding place and never scared of light.

It's been 3 weeks. I wouldn't worry just yet. Wolves go months at around a foot (30cm). My old curu at 8" took I believe 2 months to eat for me.
