Leah; the title of this thread you used, & your opening post, reads like a protest against this hobbie, & a protest against a particular public aqaurium, even if that was not your intention.
A protester against this hobbie, posting on this forum would rightly be considered a troll.
You asked for peoples opinions & you got them.
People would feel defensive, & react. Many people are fed up with the self righteous moralistic lecturing from groups & individuals telling every one else how bad they are to nature & animals.
You have been, to some extent, misunderstood in this thread.
Offensive posts have been removed.
Forget about this thread, ignore the taunts & move on.
A a newbie, continually returning to this thread to aggressively argue, with sarcasm, is not a good look.
You are an experienced hobbiest. Go & browse the forum & maybe you can give some good advice to someone who needs some help?
