| Double | Two lobes of equal size with appearance of being split |

| Halfmoon | Very rare rounded tail that is stretched 180 degrees |
| Heart | Partially fused twin caudal fin |
| Round or Fan | Small to medium in size with pronounced rays that lead up to the end of the tail |
| Short | Finnage that is small |
| Single | Common one-lobed |
| Veil | Most common |
