It depends on the the species. H. lunulata and other tropical species should be fine in a 24 gallon system. H. fasciata and H. maculosa require cool temperatures. The real problem here is keeping the octopus from working its way into the fitration section of the system or escaping. H. lunulata will crawl above the water line and if an animal got into the filters, it could be dangerous trying to extract it. When working with blue-rings it is essential that you know where they are at all times.
Since you asked the question, I assume you know the risks of envenomation and the difficulty of keeping these animals for any period of time. For most people it is not worth the effort or risk.
