Actually yes, I keep mine however in a 100 gallon tank with my huge pleco who won’t fit anywhere else any more. They get along great the ropefish never leaves the eels side and they even eat right there together. They use the same hide and never hurt each other. My rope fish actually even jumped out of the tank when I removed the eel once to put in my 80 gallon eel tank and once I put back has not jumped out yet or even tried to. So in my experience they get alone great. Getting attached to each-other even. My eel sticks with the rope fish as well his not just all him. She will follow him around and I have seen the pleco attempt to push the ropefish out of its way and the eel actually went after the pleco, she didn’t hurt him she just bumped him and got him away from the ropefish. They get along great if u have the tank size for them both.
