No, but I gotta rethink my 10g. I was dumb and lost the three fish in it. It was really a backup tank and for whatever reason I was getting some cyano in it after over a year of it being perfectly fine. I dosed chemiclean and didn't add an air stone, it gets tons of surface air and bubbles naturally. Suffice to say, it still removed enough oxygen to kill the fish in one day... I dosed it at 11pm, next morning for work they were fine (it's in my office next to my computer), then looked over at 12 and they were gasping. I threw one in the other tank, but it didn't make it.
Zoa's in there are fine, some other things got moved to the other tank, some just got nuked. Mostly random mushrooms.
What I don't understand is the order or things. The gorgonian (not the NPS one which is fine) just absolutely melted and I think it poisoned the tank. The other interesting observation is that there were a TON of bristleworms which croaked too, more than I ever knew were in there. I think that added to the bioload in a way I never knew and then the die off was a chain reaction. I'm not sure if I want to restart the 10g, it was really for extra zoa's from the main tank and shrooms.
Some shrooms I don't have backups of... Zoa's I do.
