There are some tilapia but I can't think of one that is pink. In fact, there are very few fish that are pink. Pink convicts and pink kissing gourami come to mind but convicts are South American and gourami are . . . uh, not cichlids.
Good Morning, haha. I'm short. Too short.
Fishy, a few other tetra ideas. You could do emperor tetras. They get quite big and very pretty.
Also, not colorful but interesting are blind cave tetras. And rummynoses may work, at least for now. When your angels are full-grown, maybe not but right now they would work being a max 2" or so.
EDIT: Some parrot cichlids are dyed to look pink. :/
