You asked me a question that I had already answered. I didn't want to answer it again, but since you feel the need to be rude and insinuate that I was acting like your father, I will explain it again.
As I said before, giving your catfish to a public aquarium was a more responsible choice than allowing it to die in a tiny tank. However, the more responsible thing would have been to do what it needed in order to keep it. See, it's not really responsible if you're just passing on your bad decision to someone else because you don't want to deal with it. Sure, they had the room, but Public Aquaria fills up very quickly with big cats, Pacu, Arapaima, Nurse Sharks and the like for a reason.
Now, you have another large cat, and rather than making the decision to do whatever it needs, you've essentially set a limit on how large it can grow.
Not that it really matters to you, but I'm not a guy, and most likely have no resemblance at all to your father.
