Deimos can be seen with a goofy grin, he just seems to be having a chill and fun day. Deimos would be swimming in his tank, his electric blue fins on his tail seemed to shine under the tank light causing it to shimmer. He seemed to be waiting for snacks, or awaiting for his feeding time which consists of raw meat slabs.

He waves at you before he swims over, tapping the glass to get your attention. He seems to be in a playful mood.
