A few days ago I added a juvenile chainlink eel to my 150g display tank. He's a little thicker than a sharpie and maybe 10 inches long. He's proven to be a bit of a houdini - I had to tape down the corners of my tank lid cos I was worried he would squeeze out. Today I found him in the rocky section of my sump. It's about the size of a 15 gallon tank.
My best guess is that he squeezed through the slats in my overflow. I could easily catch him and put him back in the display but I think this could be a recurring problem.
Should I just leave him down there until he's too big to slip into my overflow? I honestly can't think of a way to seal off all of those vertical slats...
