harsh....
but understandable!
if you want reasons (excuses, if you will):
for myself, I already have a four foot aquarium in my living room, I have no financial means or even physical room to sustain another tank, even if it is only coldwater - esp as you stated earlier that they would not be comfortable above 22ºC (25ºC being "extreme") and where I currently live, that sort of temperature is going to be remarkably difficult to attain! My tank at present is set at 23º, and yet it has never gone below 25º!
So, unless I can afford a chiller unit, I can't afford this. Maybe, sometime in the future, if my present tank carks it, or I find somewhere else to live with more room, I would definatly think about helping to sustain an endangered species - what bigger thrill than to help bring a species back from the brink of being lost????
All I'm saying is that it's fine for you to vent, but don't automatically assume that because you have had a low level of interest, it doesn't mean that we're not interested, it may possibly be (certainly in my case) that it's not a feasible option at present.
