As a newbie to both this website and the saltwater hobby, I blush and feel a bit like I'm interrupting a family spat. But I couldn't help but hear my mother's voice in my head as I read this thread. She was saying "Now, now. Don't make me separate you!" I know I'm running the risk of sounding awfully annoying but you can always ignore my 2 cents whenever you like: so here 'tis: when hubby and I first started researching and receiving advice from online friends, websites, and also our LFS friendlies, I began realizing how much work it was going to take to create and maintain this water world in our home. I've never been a mostly lazy person, but nor have I been a particularly hard worker. so "playing god" wasn't exactly a thing I wanted to try. But now that we've begun, I can see both sides of the argument on this thread (since my mind is caught in the middle). I yearn to be in the neutral between both stances here...my 2cents = nothing wrong with purchasing stock that helps with the ecosystem of the tank AS LONG AS you take into consideration the care of the animal in this role also (i.e. after the problem is resolved, feed and care for him/her properly even when there is no existing problem for him/her to solve) And I would in addition do my job to look for the root cause in case it could still be a harmful situation to the stock. Sound too "nose up" for you? I welcome any responses as long as it is in good nature. I will not respond to out-right attacks.
