Hi........
If I compare natural feeding behaviour of a native fish here in Germany,called pike (Esox lucius)..........
The pike also eats a duck,or a swimming mouse if it can get it..........
But this will allways be sometimes and not quite often I think..........
Normaly they feed on fish...........
and I think it is the same big snakeheads are doing in nature!
I know someone who is feeding sometimes frozen baby rats,or a frozen mouse to his Channas...........but only once a month at maximum........!
And they are fine!
But do not do this as often!
I do not feed this to my snakeheads...........and they are fine,too!
I even breed them!
Also I do not feed beef heart (is it the word???)
