Wrong, IMO...
It's because of people like this mess it up for the rest of us who might be able to take care of and keep more exotic/rare wildlife because they either dump their pet one day, or sell/give it away to someone who has no idea what they're doing and kill or release it themselves.
And to those making smart ass remarks to me, grow up. Unless your criminals yourselves, you don't need to adhere to the juvenile "DONT SNITCH" code. If you truly appreciate fish keeping, you'd understand the attitude about this.
