For one, fish don't "consume" their antibiotics. They swim around in a bath containing them, absorbing them through their gills and skin (I suppose - I am not a fish biologist).

When humans take their antibiotics (orally), they toss them down into a very strong acid bath (their stomach).

Drugs are formulated differently depending on the route of administration. Nothing could be more different than how fish and humans obtain and process their dose.
