It's not that people were trying to bombard you, and you are welcome here to talk about tanks, systems, and saltwater in general. BUT, when the folks here see you doing something that is obviously cruel (or at a minimum, poorly thought out and not well-researched), they will let you know. The folks here start gently, asking you to do some research and simply fix your mistakes. We understand that everyone here has made some mistakes, especially when first starting out. We understand that almost everyone here has been misled by a fish store employee at some point in time or another. But in the face of experienced, knowledgeable, well-intentioned advice, you persist in making said mistakes and in fact defend and justify such acts of cruelty, we tend to get frustrated. At that point, we do tend to stop phrasing things gently, and just speak plainly. In the end, we really want what's best for the animals involved. It's not to hurt your feelings; it's to prevent the cruel treatment of creatures that can't speak for themselves. Yes, even if it's unintentional, it's still cruel. And after you've been informed that what you are doing is cruel, if you continue to do it, then it's intentional cruelty, and that is something the majority of people here can't abide, and don't want read about.
So yes, when we hear about you cramming not one, but three fish in a tank 1/6 the recommended size for a fish of that kind, and those same three fish are being housed in a tank that couldn't reasonably be expected to house even one fish that size, we will let you know what you are doing is wrong. When we then hear a bunch of excuses as to why what you are doing is ok, we will let you know in no uncertain circumstances that what you are doing is cruel. And when you let us know that you are moving those three fish from a proverbial closet with a bucket to what amounts to a one bed hotel room with probably 4-5 + current occupants (upping the count to at least 7, probably more), you cannot possibly expect us to think that's much of an improvement!
We are trying to help you and the fish. We tend to stick up for the fish, since they have no say in the matter. Please don't take it personally. None of us have a personal vendetta against you. We just want you to see the error of your ways, and correct those errors so that no living creature has to suffer for the hobby that we all love so much.
