I'm just curious. Will a BGK and an elephant nose clash? I think they are from the same family Mormyrids. And I have heard these fish tend to get aggressive, which is why they recommend if you get these keep one or many never a few. But BGK's are from South America and Elephant Nose's are from Africa, so the two would never interact with each other naturally, so would they clash? Naturally they'd never meet would they still know they belong to the same family, we classify things into families but their animals. How would they know?
