Chinese Algae Eater and Knife Fish combo.. Any problems, experiences, etc?

[PaiLum92]

Looking to get a new fish, have a new experience..

So, I am thinking about trying my luck with a Knife Fish..

I am wondering though, I already have a Chinese Algae Eater, and I was wondering if anyone has had experience with this combo, a Knife Fish and a Algae Eater..

I’ve mostly dealt with Poly’s, so I know Algae Eaters and Poly’s don’t mix but what about Algae Eaters and Knife Fish?

Also, tank is a 72g, 4 or 5 hiding spots..

Is this an OK Combo, or no?

Thanks..
