Many fish eat riverine plants and plant parts (seeds, fruit, roots, fronds), some of which are semiaquatic, while some are mainly terrestrial during low water times, but riverine or aquatic during high water. Then, there are are fish that are either obligate or facultative rheophilic in their feeding habits, feeding on flowering plants (not algae) that grow on rocks either submerged, or at the interface. A lot of large silver dollars, and some characins fit that bill.
So to me, part of the the distinction between aquatic and terrestrial plants is purely our own perception. On the other hand, I do worry about traces of pesticides that may be in certain terrestrial crops, aimed at protecting leafy things from insects and slug damage. Of course one would rinse them well prior to use, but there is a level of concern.
That said, I include a number of veggies among the varied foods I give my fish, including cucumber, garbanzos, peas (& similar guandules), romaine, some spinach, and seaweed sheets (nori). Those are rotated with frozen, a variety of flakes and pellets.
