The eyes are distorted by the flash. Nest in back.
Love must be in the air, or water as it is. I'd noticed last week that one of the two female Pearl Gourami had fattened up (usually indicating they're full of eggs and ready to spawn). I considered moving her and the male into a separate tank but I hadn't seen the male build a bubble nest yet (male spawning indicator) and didn't know if he would be ready. I also don't have easy access to RO water, which may be necessary to hatch the eggs. RO water lowers the hardness of my tap water. This reduced mineral content is reportedly necessary for Gourami eggs to hatch.
Today I noticed the male tending a bubble nest. At first I thought he was building it, but I saw him running the females off. He appears to be in post-spawn-egg-guarding father mode.
