Here is my take on all of this...
I have gone over all of this before with him. In fact, if you search old posts, about a month ago when he was wanted to purchase an anemone, I advised him that this was a bad idea. He didn't take the advise and purchased one anyway.
At this point, I can only continue to offer my advise to him even if it is not taken seriously. I could sit back and just not do anything, but I think it is prudent to continue to try and point him in the right direction, if for nothing else, to keep the animals alive. Hopefully it will start to sink in sooner or later.
When I first started out, I got all kinds of advice that I didn't take. Now that my reefing abilities have gotten sharper and I know the error of my ways, its easy to say what I should and shouldn't have done.
I am not defending him or any of his actions by any means. I just know (as we all should know) that we all make mistakes even when proper advise is given. Hopefully as he matures in this hobby he will not make the same mistakes again and he will the current problems he has.
BTW, I am in agreement with all of you in that the tank is way overstocked. Several of those fish need to go (as well as the anemone), a proper
QT method is needed, and possibly better filtration.
