One of the biggest advantages in the game right now is increasing your population. Torians are aquatic, which means that they get amazing Hydroponic farms instead of Xeno farms, but the technology is further down the tech tree. Getting farms (thus cities) is more difficult. However, aquatic races also have the best research facilities.
Usually, when playing aquatic, I go for the basic lab buildings to jump-start my tech. Then I go straight for the Hydro farms. Then I build cities, and research goes crazy, as does production.
Speaking of production, the aquatics also have the Central Mine, which gives +1 raw production (social, military, wealth, research all benefit from this) and +1 to All Construction per adjacency.
So aquatics take a lot longer to get their economy up, but once they do, they have major advantages.
