Hey guys I need a little help here. I'm new to owning Knife fish and recently received a Clown KF. It got a new upgraded larger tank and the CKF is doing great eating a few too many feeder fish lol. My question is will it be ok to put a 2" black Ghost Knife fish in the same tank as my 5"+ CKF? I don't want my breeding Angel fish in my other tank to nip at my BGKF. Just trying to make sure my BGKF has a chance to get bigger and thrive with my CKF, just not sure if it's safe at the moment . Thanks
