Ropefish are tolerant of a wide range of water conditions, so it would probably do o.k. in the high ph cichlids are kept in (although not ideal).Just a question about that ropefish. How do you think it would fare with a 9" Blackbelt Cichlid? He isn't "super-aggressive", but he has hassled every other fish I've had with it until I had to remove them (live or dead ). I'm adding him to a new tank for Christmas, and I'm wondering how you think they would stand up to a larger Cichlid? (he will get bigger, too! At least a foot, I expect). It's about 120 gallons and I'd like something else for interaction and show.
