clown knifefish mix with koi fish...

  • We are currently upgrading MFK. thanks! -neo
shouldn't be having koi in a tank in the first place lol as long as it isn't aggressive then i guess it should be fine..?
 
Should be fine, but the temperature requirements for these guys are different. While CKs are tropical, Koi prefer cooler temperatures. Since it's a pond setting, I'm assuming you live in a tropical climate? If temperatures drop below 72F (lowest I'd go with a CK), you should have a tank to move the CK in during the colder seasons.
 
as stated, i wouldn't mix both for the reason that their temp variance is different from each other.
 
I have a 18" CKF with 2 13-16" Koi, they don't even know each other exists. My CKF is pretty tame though, not to mention they have 1,000G of water to swim from. Must be tired from all the swimming = no aggression.
