[Wallion Aquatics]

What fishes can stay in the tank with Knifefish? Heard Knifefish are aggressive.

What species of knife is that? Hard to tell from above.

The picture isnt black ghost knife. You sure?
Not sure those are clown knives either. But they look closer to that then black ghost.

Looks more brown ghost knife or African knife

High potential for African W Wallion Aquatics can you get a side photo, even in a net?

 

[Wallion Aquatics]

Okay..when I will take a picture when I get home.

It's from Africa by the way...

Almost definitely Xenomystus nigri then, very calm knives generally. They can wreak havoc if the pecking order is disturbed but that's only from my single experience keeping a group and may not be true for all African knives.
