Do Black Ghost Knife Fish Get Along With Peppered Corys

[expert11]

once it got big enough, yes. since the BGK will reach full-size well before the end of the cory's lifespan, there's not much point in mixing them.

a good rule of thumb is that if it's alive and it fits in the fish's mouth, he'll probably try to eat it.

A BGK would not eat adult corydoras, even if its mouth were big enough their armoured bodies and spikey fins make them unappealing as meals to all but the largest predators. Slim fish such as tetras, danios and smaller barbs could end up as snacks but the bulky shape of corys gives them some protection from predatation.
