Dwarf snakehead with koi/goldfish?

[chineseguy]

Anyone have experience keeping dwarf snakehead (channa gachua) or channa bleheri with koi or goldfish in a pond? They are said to be more peaceful and can be kept with other peaceful fish as long as they are too big to be considered food. Could keeping them with large single-tailed goldfish and koi be possible long term? or would their long flowing fins be seen as a snack for the snakehead?

Hi OP! I'm in China too. It gets 5 celsius here in winter. Can channa bleheri live well with such temperature?

the answer would be no, channa is more than likely to take a bite out of its tank mates

want to create another thread, but the answer is here... sort of.
can bite other fish fins.
bite cause of being a fin nipper, or something else?
