at my tanks happiest times, almost impossible to keep up with trimming. When corals are in the zone and your tank is tweaked to that sweet spot (whatever that magical, mystical spot is), growth is incredible and hard to deal with all the frags--really no joke. Also as you trim, a colony will inevitably either break in half or dislodge from the aquascape, both issues are a pain to deal with. Most of those "problems" get resolved by moving out of that sweet spot, either by boredom and reaquascaping or issues under the category, stuff just happens (things like operator error, equipment failure, pushing the envelope, vacations, on and on...)
Dead fish or dead coral are awful. These are all beautiful creatures that we have chosen to be responsible for and when they die or languish, it is really hard. I don't wish to be misunderstood, I enjoy eating fish ( not from my tank!). But these critters were taken from the ocean purely for our enjoyment and so to have them die is just bad on so many levels. There does seem to be an endless supply, but we all really know that is not true. The reality is that mortality is high in reefing. It's always great to hear about a twenty year old fish in someone's tank, or a reef tank that has been around a long time, but those examples seem to be the exception and not the rule. The majority of my current fish have been with me for some years but there are far too many fish that I have not been able to keep alive for many reasons. The same reality is true for coral. It's a good thing that you can't hear moans or screams through water ( that may be a bit too extreme on the morbid)
There are moral and ethical considerations in reefing. How one values life and beauty is a very personal issue. I'm sure there are lots of views and perspectives
So ultimately, I am, to my own dismay, somewhat callous on the mortality issue. I try to be conscientious in terms of reefing. In addition, to all of the factors listed above, it is incredibly expensive to lose any of these creatures. So like everyone else, I try my best to be vigilant with my reef keeping skills. And I read all these threads, looking to find some glimmering thought that will enlighten me to ultimately improve my tank.
That also means, I peruse through a variety of bizarre and inane thoughts and comments along the way. Probably makes my life richer for it. But I am undoubtedly impressed by the variety of thoughts (or lack thereof) shared on the forum daily.
