The hourglass host - z_sp 0.565 SDSS J122716.57+585427.7 - seems to be a merger, with some #green fluff besides:
In the same rich cluster - apparently (maybe it's just a foreground?) - is z_ph 0.37 SDSS J122708.85+585351.4, which looks #green, and merging:
There's even what may be a Green Pea (z_ph 0.35 SDSS J122710.95+585331.8; #green, by definition):
Finally, there's z_ph 0.49 GALAXY SDSS J122718.10+585322.8 and z_ph ?? GALAXY SDSS J122718.45+585321.2, which looks somewhat like gravitational lens arcs (this image centered on the former):
