I bought a rope fish about a week ago and it's missing in action. They are some good escape artists. I put him in my 125 gallon and he managed to escape yesterday through a 1/4" gap between the cover and Emperor filter. I found him hiding inside the filter and returned him to the tank. Well tonight he went MIA again. I've checked the filters, overturned all my rocks, and I sifted through the substrate and couldn't find him. I searched all over the house with no luck. I don't know where the thing could have gone. It's about 10" long so it's not hard to miss. I'm stumped!! This sucks!
