Sororities sound like a recipe for disaster. Not what I want!
My dumbo HM had an internal injury 5 months ago and is no longer very active. He got caught up in a current and was slammed into driftwood sideways. Now 95% of the time he is resting his giant fins on brazilian pennywort at the water surface so he doesn't have to swim around. He is in good health, just looks like a paraplegic fish.
A couple weeks ago I added harlequin rasboras to my tank. Give him something stimulating to look at. I love how active the are! That's when I thought about upgrading to sorority community. More fish, more activity.
Since he doesn't swim much and prefers still water, I thought about placing him in a larger breeder box/specimen container inside the tank with a community. He would have floating plants, fish to look at, and keep his own territory.
RussellTheShihtzui - About a HMPK male or 1 female, I can imagine shorter fins would work better in a community. Be able to zip around faster too? That is probably what I would want.
My dumbo HM is a beautiful fish, but his fins are SO big and get caught up in the slightest current. I wish I could help him out and give him a "hair cut."
