I was aware the amazon fish getting into people's bladders is an unintended consequence of its behavior, but I was working off the assumption your fish would do it on purpose. The fish would have adapted to infect a creature's bladder specifically because of the lack of the necessary mineral components in its normal habitat. The easiest answer to why it would require those minerals in the first place if they can't be found in their usual habitat is that the minerals were once abundant in /meat/'s waters but environmental changes over time eventually made them scarce, yet the fish found that it could still easily find those minerals in urine. Specifically the urine of primates, in this case, since we want these fish to be able to infest humans. Just swimming around aimlessly hoping a monkey pees in the water near them isn't a very good survival strategy, so the fish learned to actively seek the source instead. As for the problem of a water-based species evolving to rely on a non-water based species, my assumption was that these fish of yours would enter the urinary tract while a creature was bathing, or even just cooling off by resting in water, something that should happen with fair frequency given /meat/'s tropical climate. This is why I said the biggest problem would be how the fish returns to the water after reaching adulthood. The fish invading a host's urinary tract while the host is in water is self explanatory, but I'm uncertain how the fish would be able to ensure it exits back into water after it's fully grown.
