So I thought I’d make a thread showing them since now I got both. These get misidentified all the time and people can’t tell which. Really in person they are easy to tell apart. LSOH have lighter green with smaller rings and skinnier and longer tentacles. Rainbow eclipse have a darker green and more detail with overall polyp size being slightly larger.
