My shrimp got cooked!!! Shrimp scampi anyone?

[Shorty]

I'm just starting a planted tank and I got some ottos. I recently got a
few japonica (amano) shrimp to eat some of the algae that the ottos
won't. My pH is around 6.8-7 kH around 4-5 and temperature 78-80. I
woke up next morning and they were orange/white.
What happened?

I had the same thing happen a year ago. In my case I found that when I
took some of the shrimp out and put them in tap water they recovered. That,
of course, indicated that it was something with the water. It was pretty
amazing really. The shrimp had just stopped moving and had turned mostly
white. Within an hour of being in the tap water he was swimming around and
acting his old self.

Are you injecting CO2? My guess at the time was that I was over
saturating the water with CO2 and that the shrimp were sensitive to that.
My kH and gH had climbed, the probe was not calibrated correctly and the CO2
spiked :-(

So you brought the shrimp back from the dead? Mine looked not only
white but also orange/red. They really looked cooked and dead. I hope I
did not get rid of shrimp that I could have brought back alive.

I am just starting the tank and I am injecting CO2 to promote growth so
that was probably it. I read that the invertebrates are very sensitive
to water condition changes.

I guess I will leave the shrimp for a later time when I have the tank
more established.

Thanks!

I only rescued the one actually. He was a pale white, not all the way to
orange like the rest. I imagine he had passed out and the fresh water
revived him.

Yah, more variables to balance.

Good idea, although they are a fun addition. The only problem I have now
is that the shrimp I have all seem to hang out in the same spot (plenty of
food and cover there) and don't move around the tank.

Uh huh. Ammonia != 0.

If they're pink or orange and not moving they're dead. A pink shrimp is
a dead shrimp, period. But if they look mostly normal and are just lying upside
down with all their little legs curled up not moving then yes if you put them
in clean water there's a very good change they'll survive.

I had this tank of crypts melt down once and had to rescue about 19 ammano
carcasses. 16 got better when put in clean water and are still around a year
later.

Is that the usual cause? The tank had been stable for some time (6
months+) but then I can't rule it out either, as I don't remember testing at
the time.

I would prefer that explanation, as I've typically run CO2 around 30ppm
and haven't seen a die off similar to this with any shrimp.

They are definately hardy little monsters. I heard a scream from my wife one
day when she was dusting the stairs - turned out to be a shrimp from my tank
sitting on one of the treads had made her jump. I can only guess that it was
on the inside of the tank lid when I had done a water change a couple of
hours earlier and had fallen onto the floor to be found by one of the cats
(unless it climbed up there it's self : ) ). I put it back in the tank after
rinsing the dust off it and it's still looking happy today - that was over a
year ago.

It's the most likely. Shrimp are actually pretty hardy otherwise
and endure adverse conditions that would kill any fish but they
make up for this if you even say the word "ammonia" in a room
containing shrimp tanks by promptly dropping dead.

Thanks, that's important to know!
