Getting picked off one by one

[PorscheReef]

Monday purple pseudeo dead.
Tuesday morning yellow tail damsel dead.
Tuesday Night large potters angel dead & Occ clown laying
on side breathing heavy. Performed 30gal water change and
watched tank for about 3 hours all other fish seem ok and
tank parameters normal PH 8.1, trates 0, trites 0, amonia 0, alk 10dlk and calcium 460ppm. This is the sort of thing that makes me want to get a new hobby LOL.

I think this is one of those cases where without a disection of one of the dead species we won't be able to tell you whats going on. I could be somekind of internal parasite or infection...

What are some of the commonalities before each death. Are they symptoms that resemble the clown? Are there no symptoms before death? Are there anything out of the ordinary after death. Ie. fish dead with mouth open, etc. Tank wipeouts with mystery deaths are uncommon to say the least. If it comes to the point where everything dies with no symptoms in that tank, I would tear it down clean everything and start over. There is something nasty in that tank, it may be a foreign substance that was introduced into the water that traditional tests can't test for. Lotion on hands. Cleaning chemicals used around the tank, it doesn't take much to saturate the tank, and it doesn't take much saturation to wipe out the system.

Psuedo showed no signs before death.
Potters angel after dead look like something wrapped it like a mummy like something out of CSI tan thin film almost mucus like
and damsel out of nowhere.

They got the ich, I quarentined both clown fish and performed
hypo treatment with a little copper additive. Just gonna have to wait and see.

Seems to be a tough call of what is going on with your system, especially when none seem to have similar symptoms. Treating the ich is the next stage I guess, while there are no fish in the display, weigh your options of maybe doing a huge water change or maybe break it down and setting it back up. Check and see what others' opinions would be though.
