Hi Marie,
No one kicked anyone out. We are all just a little weary of discussing the ethics of what we do as if there was a fixed thing called ethics. What one person thinks is ethical is what another person thinks is inhumane. No one asks the fish. Until we hear from them, your guess is as good as mine. The only surely ethical thing to do is to leave them in the ocean. By this definition of ethics, all aquarium keepers are un-ethical. Given that this forum is about fish breeding, we are not leaving them in the ocean. We are un-ethical.
We are taking them out of the ocean to breed them and hopefully keep their relatives IN the ocean. We are ethical!
Very complicated ethics there. Do the ends justify the means? No one has an answer to that one. We are weary, I say.
I reread the initial post. Here's the answer to that post. The reason that some say not to put 2 angels in a small tank is that some think it to be unethical. Some do not. No one asked the fish. Given that all systems are different, all caretakers are different, and give different levels of care, you cannot send the ethical police without knowing more than tank size. Do you at least agree that the chances of 2 angels being happy in a small well cared for tank are at least as great as 2 angels in a large neglected tank? In my opinion, if you are concerned about ethics, don't keep fish, cats, dogs, or any living thing for your own selfish pleasure. Why should they be kept dependent on you and what you imagine is required for their happiness? Your imagination is the only data you have about their happiness. You can look at a dog and say it is happy, but how do you really know?
That said, there is hardly a single thing that Man does that does not take advantage of the natural world. Good or bad, it is what we do. Humans, like other animals, cannot survive otherwise.
That said, we are all guilty as charged, and we should all be nice to one another and not hurl accusations of inhumanity without first hand knowledge of all the facts, including what the fish think. Marie, jmaneyapanda and everyone else are certainly welcome to express their views about fish breeding right here in this thread, since it does seem to be about ethics, whatever that means.
Having said my thoughts on the matter, I bid you adieu, God bless, and good luck. I am too weary to post further. Gotta save my energy to go siphon fish poop.

Kind of makes me feel like I should be providing this in his diet, but we won't tell Matt, ok? 
lol
I suggest you read the initial post - the question was about the number of angels in a given tank size.
