I have never heard of that one before. I assume that hormones dont last very long in either the aquarium or the environment. Plus the concentration of fish is much lower in the wild than in aquariums. Lets assume a pond can support 50 pounds of largemouth bass per acre (which is a not so atypical average) and lets also assume that each of these bass weighs 1 pound, which would make them about 13 inches (27cm) each. So if our 1 acre of water has an average depth of 5 feet, that means you have 50, 13 inch fish occupying 1.6 million gallons of water! That's a big aquarium! Obviously there are going to be other species of fish and other organisms living in this water as well, but you can see the concentration of fish in a natural body of water is hugely lower than in an aquarium, so there is little opportunity for hormones to reach any meaningful concentration in the wild. The volume of fish is far too small compared to the volume of the water that they live in. As for aquariums, like i said i am not familiar with this particular topic. I assume that any hormones would fairly rapidly either photodegrade or biodegrade, just as in the wild. This is just speculation on my part, though i have never heard of it being an issue before.
