My Wolf fish( Hoplias Malabaricus) won't eat?

[Kristianfborve]

It's a small wolf fish( Hoplias Malabaricus) that's around 9 cm. I got him 4 weeks ago. I've placed him in my tank with my 3 dwarf snakeheads( Channa Gachua) that's 15-17 cm. I've tried to feed him at the day and night, but when I watch he doesn't eat. I've fed him with discus bits( the pet store i got him from fed him with discus bits). The snakeheads eat oxheart/beefheart, but the wolf doesn't eat. I don't know if he eats when I'm sleeping. He doesn't seem to breath heavily, but do you know something I can feed him with, or something I can do to get him to eat?
This is some pictures of my wolf:

I would separate the wolf from the Channa. It's prolly stressed from them. Once separated. I would try some cut tilapia and earthworms. Get a divider. Once separated I'm sure it wolf will eat. The other thing is Channa are sub tropical and is ur water temps low? This not good for ur mala. Do u see fighting b/w ur fish?

I think ur Channa is dominating the wolf. Once it gets bigger then the tides will change. As I think it's a gaucha but not too good with Channa IDs.

I've never seen any kind of fight between them. Thanks for the response!

He could just be stressed from fear of the size difference which can overwhelm him and cause him to focus on staying uneaten rather than eating

Thanks for all the help! I went to the pet store today and bought some chemicals and a pinkie. I gave my wolf some hiding space and the pinkie..and then I turned off the light... After 10 minutes he began to eat! Is it good for the fish to eat pinkies?

A lot of times my Wolf would not eat in front of me no matter how long I sat there. But it would be gone in the morning whether it was commercial or live.

It can have a pinkie once ina while. But I would do pellets/frozen/krill.
