I was one of the ones that suggested it MIGHT be illegal. I suggested on the grounds that IF somehow one were to survive (as you and otthers have pointed out is very unlikely) then that would be considered releasing a non-native species into the waters which is illegal in most states to protect the wildlife. I understand the water is treated, chance of survival is next to impossible, but not impossible IMO, as we have seen many fish adapt and somehow survive in crazy places. So my argument was that the betta was non-native and technically that person could be releasing it back into the wild and although very unlikely if it were to survive who knows the effects it could have...Is it illegal, really? On what grounds, if so?
Not that I don't think it SHOULD be illegal, but I'd be pretty surprised if it were considering the general lack of laws protecting fish. Also, sewer water is pre-treated before being dumped back into waterways, so no live fish is going to survive that journey, I don't think.
