#fish are so modular there's so much you can tell by their diet/habitat just by looking at them *_*

Quick! Is rohu a surface feeder????

whoah, never heard of a rohu before! catchy name.

apparently it's a filter feeder, but it looks like it could pretty handily eat from the water's surface too. surface-feeding fish usually have very superior (upwards-pointing) mouths, flat heads, wedge-shaped bodies, and far posterior dorsal fins, all designed to help them pluck floating food without having to swim at an awkward diagonal angle or stick their fins out of the water, which seem to apply to the rohu.
