Putting 'Syngonium' into Google which was what you said your tag(s) read, gives you what looks like the background plant in your picture.
Seems to be a terrestrial plant, may be able to be kept the same way as pothos though.
Have you get any better photos of it?
Anything variegated is generally a terrestrial plant, also when you take the plant out of the water a true aquatic will generally not be able to stand upright on its own whereas a terrestrial plant will.
Exceptions to this would be anubias as they grow emersed in their native habitat, and emersed grown aquatics such as crypts or sword plants. However, these plants will be able to make the transition to a full submersed environment while a terrestrial plant cannot.
Generally, if a plant looks like it belongs in a pot, it probably does.
