Start saving for a large tank now. A rope may not move a lot, but like any living creature, it excretes. It needs space. It will probably be able to persist in your tank, and will move a lot less than it might as it gauges its surroundings. Methinks you're trying to fit the fish into the tank, and not making the tank fit for the fish. They are a very sturdy, survivor species that can take a lot, but since you'll probably receive a small one you do have time to adjust before its growth is slowed by conditions.
They're "hot" right now, as predators, even shy ones, are in fashion. I've never kept one, but I have handled a lot of them as they arrived and passed through the supply chain. They are very active in holding tanks. If I were into predators (I'm not) I'd consider them too large for my largest available tank. Plus I don't have any 4 foot tanks with no other inhabitants. They hunt at night, and if it fits in their mouths, it's gone.
I hate pond snails. I like ramshorns. It's because pond snails are voracious fish egg eaters though. If you don't breed fish, it's less of an issue.
