Do shrimp play dead, or is it really dead?

for reference, what keeps getting sensored out is spi_ke... for some reason the filter censors out that one

Are you finding the upside down snails in the same areas? If a snail or crab gets close to my clowns host frogspawn, they will nip and flip them. Six liner does it too. I right them in the mornings and they are fine.

Ok, so everything has been doing ok for a while, but today we did a 50-60% water change, and it killed our two firefish. Everything else seems to be doing ok, the shrimp are doing better, but for some reason the firefish both keeled over. I got a new test kit for my levels, and they are all ok, pH, nitrate/ite, ammonia, all just fine. Salinity and temp are ok too. What is going on???

Is there anything I could be checking in my tap water that might be causing this??

[Bill S]

Uh oh. You are using tap water???

[labrown]

yep and adding essential elements to the mix. We haven't had any problems with it before, and have been doing the water changes monthly from our tap for at least 6 months. We don't have hard water either...
