Re: [GSAS-Member] Fun Present
Well in reality halocaridina rubra are an incredible species of "super shrimp"
known to live more than 20 years in captivity with the proper conditions
http://en.wikipedia.org/wiki/Halocaridina. Seven years is not really that long
for these guys.
There are numerous other websites including this one:
http://www.fukubonsai.com/M-L2d.html on the subject. This website shows the
research of Dr. Wayne Nishijima of the Univ of Hawaii. It describes in detail
why the ecosphere is flawed. A Dr. is credible enough for me.
" Each time the opae-ula molt, they step out of a larger shell and a new
smaller shell hardens around them. Shrinking opae-ula are the same as skinny
people or animals whose gaunt appearance and ribs sticking out are clear
signs of being malnourished! If children or animals were starved as badly as
these opae-ula, the parents, owners, or zookeepers would very quickly be in
jail!
The low indoor light where opae-ula jars are kept do not
support the growth of high-energy algae equal to the type of algae that grows
in the full sun in the anchialine ponds. The algae that grows in low light
just does not have the nutritional value even if the opae-ula ate enough to
always be "full." They survive but their shrinking indicates that they are
malnourished.
Anyone observing opae-ula in their natural habitats knows
that opae-ula are voracious eaters! A healthy pond producing opae-ula has
very little algae growth as the opae-ula is constant grazer that keeps the
algae down. A pond with a lot of algae is a pond that likely has exotic fish
and threatened opae-ula!
Anchialine pond algae growing in full sun is believed to
contains a significantly higher amount of nutritional value that the algae
that grows on the inner walls of opae-ula jars that are kept in low indoor
light. Fuku-Bonsai theorized that chill-dried spirulina provided the same or
higher nutritional value of the full sun anchialine pond algae and it seems
too! "

seven years sounds pretty good. The torture-sphere
thing sounds like some pointlessly bitter hyperboly. People say a lot of wacky
things
on their websites, but I doubt that the average person could keep a tank of
shrimp
going for seven years ... or even a year when you get right down to it. We
should worry
more about those poor Sea Monkeys (note: just kidding).

I have a small Eco Sphere. It started with 3 shrimp. Today, about 7 years
later, there is one left. Hey, I think I should name him!
I would like to see the alarmist claims vetted scientifically, for example,
analyzing the water quality from a sphere that has been in use for a long
time.
It's not an ideal environment, but don't know that I would call it a
"Torturesphere."
I have accidentally caused much more grief to higher life forms in my
aquariums, I think.
