That shrimp I found Wednesday night? Mystery death. Parameters are still good, been running carbon (to no avail, it seems), and have found 2 more dead since Wednesday. It's a shame, because I've also found 2 molts, so some are growing well enough, and the bladder snails absolutely love the tank. Sadly, that's not enough for me to keep the tank indefinitely, just for bladder snails. I'm afraid to move the snails to another tank, because they'll possibly infect another tank with whatever is going on in this one. So, after the approximately 18 die off (because I'm definitely not putting them in with my survivors in the 55), I'm nuking the tank to oblivion.
What's a good price for potassium permanganate? I'll get some and use it to disinfect the java fern/driftwood and rock. Everything else will either get bleached or thrown away. Bacopa is now cheap, as I've got more than I reasonably need in my 55, and the peacock moss seems to be doing quite well in my 55 as well, so I'll be able to move some of that back at a later date, too.
