while my position may seem hardline, I assure you it is not. To define:
For animals with a natural (wild) lifespan of, for example, 20-30 years (as many large community fishes we keep have, such as Angels, Tangs, Serranids, etc) ... I'd be grateful to at least see them making it to ten years of age in aquaria. Longer would be nice. But there are great values and benefits to the use (sacrifice if you will) of such organisms even prematurely... education, inspiring young and older minds alike to greater empathy, global awareness of reef science issues, etc that really do pay great dividends on the species and all reef creatures for their use (captive keeping).
I recognize and treasure that dearly. I'd like to believe I'm living and practicing it by the mentoring work for other hobbyists that I do.
But what chides me is the very casual and flip nature that some hobbyists take by chalking up the lives of their creatures to "disposability" for the sake of selfish aesthetic preferences (or jusy plain laziness or frugality to buy or maintain proper systems, avoid crowding or unnatural mixes, etc).
With so many suitable and compatible species to be had in the trade... and so much(!) free and accurate information on natural settings and requirements for the animals we keep... is a little bit of discipline too much to ask?!? Whats so hard about that?
Carrying on with the example above of a 20-30 year fish living even just ten years... what of the fact that many marine fishes can live far beyond their average natural lifespan (records at the Nancy Aq in France... Shedd in Chi-town... SF, etc).
So are we being unreasonbale then to ask an aquarist to try to keep that same, say Tang for ten years when its potential lifespan is well over thirty? Clownfishes on record over 30 years... etc.
How about anemones and corals with no known senescence? The potential to live hundreds of years?
Really... my complaint here is against hobbyists that keep a coral or fish for 5 years or less (much less in too many cases) and call that success. Its not. And its shameful for anyone that also lays claims to regard the organisms we keep as anything more than a commodity.
This philosophy (anything akin) draws the line between conscientious aquaristrs and (literally) consumers.
I will not make apologies for anything less no matter how many people are keeping anemones in coral displays, Naso tangs in 55 gall tanks, etc
Tell yourself whatever you need to get you through the night... but its still wrong if you want to lay any claim to my brand of ethics or responsible aquarium keeping.
C'mon people... we HAVE to walk the walk!
If we do not responsibly police ourselves... someone else will do it for us... and your not going to like it (legislation).
Outside of the bubble I'll call the US hobby, some frightening legislation is being proposed (and some has passed, as in EU) restricting or banning the collection of animals that we in the US take very much for granted as they are cheaply available (example... bubble coral in the US - $30, grandfathered bubble corals in Spain that can no longer be imported - folks are turning down $800).
I don't think I'm asking for much here! Its reasonable to want the animals that you and I keep to live at least one third of their potential!
I'm asking you to help us to help ourselves protect and preserve our hobby by the sensible use of the living resources.
And putting a motile cnidarian (such as an anemone) in a tank full (crowded really) of sessile cnidarians is not sensible. If it was... there would not be so many threads on anemones moving about the tank, stinging and being stung... and wiping out entire reef systems from the decay or damage (clogging pumps or overflows). It's wasteful and easily avoided with the smallest amount of effort or discipline. The folks that will preach to you that its OK, with rare exception, have had their anemones less than 3 years. Statistically... those keepers will become a statistic in time if my experience answering tragic e-mails and posts on RC and WWM alone is any indication (notice my post count here... I've answered far more over at WWM

I have some experience here. And some frustration at seeing slow progress from wasteful consumers).
Sigh... I'm gonna go and break out the big guns now. Yeah...
