Oh yes. There aren't very many "weak" Corallimorphians. Rhodactis and Discosoma are notoriously hardy. Ricordea florida and Ricordea yuma can be finicky when it comes to manual fragging. Amplexidiscus (Elephant Ear) are really hardy, too. About the only ones that I hear that might be difficult are Corynactis and Pseudocorynactis, but they aren't very sought after and multiply well by themselves.
