Hi everyone,

I was hoping to get some opinions on why my powder brown tang suddenly died. I purchased it from one of the sponsors of this site on Friday (Jan. 4th). Besides the powder brown, I also purchased a cleaner shrimp, some trochus snails, a dragon soul favia, blue xenia, large red chalice, a maze brain, and some ricordea. I had another thread on my quarantine called "I am the grim reaper of acros". Unlike back then, I have kept the cyano problem to a minimum, and have done water changes 3 out of the 4 days now of 10%-15%. Nitrates are low, and salinity is great. The temp was a little low the whole time between 72-74 (I like it closer to 76), but it was within the tolerable range for a powder brown (liveaquaria.com). It swam perfectly fine, and was breathing normally. I watched it eat both mysis shrimp, flake food, and a strip of dried algae placed in the tank for it. However, on day 3, Sunday the 7th is when it died. That morning I checked in on the tank before heading off to work. I next looked in on the tank at around 10 PM to give them a small meal for the night. It was stuck to the powerhead and dead. Not only that, but it had a mottled appearance I never saw up until then. I don't know if that was a consequence of the death or a symptom of what killed it. I can provide a picture if requested, but don't really want anyone else to have to see it. Everything else in the tank is fine (knock on wood). I contacted the company yesterday, but haven't heard back. It just seemed so sudden from perfectly fine to not alive that I'm not sure what else I could have done. If anyone has any ideas, I'd be glad to hear them. I'd like to get another powder brown in the future, but don't want that to happen again. Thanks and have a nice day.
