HI guys, I purchased a black ghost knife fish yesterday, and I went to feed the fish this morning, and he’s nowhere to be found. I noticed yesterday that he was pretty good at hiding, but I could still see him. Today, I have picked up and moved every single decoration in the tank, and he is nowhere to be found. My tank is also completely sealed because I have some escape artist reedfish. I checked the ground around the tank, anyhow. Nothing. It literally seems like he disappeared into thin air. Anyone else ever had this problem? I’ve been looking all day for him. He wasn’t cheap, either. And he is such a cool fish. I can’t understand where he could’ve gone. Any advice?
