All,
I went down to feed our fish this morning and unfortunately, our Yellow Assessor that we had for 2 months was dead at the bottom of the tank. He had been swimming and eating, regularly, this was completely unexpected. The only thing I can even say that was somewhat odd was that over the past week or so he had been hanging out in like a little alcove near one of our rocks, but that was only at night when the lights were off and he was "sleeping" or almost when he was taking a break from swimming, all other times he was fine, and usually he'd resume swimming in a few seconds.

The second thing I noticed was that our one clownfish (over 5 years old) looked like his white stripes were shedding this morning and he was swimming over in a corner. We have a shark nosed goby (who has some spots that we noticed a month ago that kind of go away and come back every so often) who was acting normally, a yellow watchmen goby who was also acting normally. We also have a Coral Beauty angel and he's usually very active at feeding time and was very lethargic almost like he was still sleepy this morning. Not sure if it was because the light had just turned on and they were still asleep, or if the other tank mates might be affected by whatever killed the Yellow Assessor, and seems to be bothering the clownfish (whether the two are related or not I'm unsure).

We have not added anything to the tank in close to a month, we've been doing regular water changes as usual, and salinity looked good this morning (1.023), so did temperature (77.4).

We don't have anything corals or anything, just fish, live rocks, and a few snails / crabs in the tank, again nothing has changed and all had been well up until today. We did a water change last Thursday, but that is all. I didn't have time to test for ammonia or nitrates / nitrites or anything this morning before leaving for work, but I have a very uneasy feeling about what I may come home to today, or in the coming days.

We do not have a quarantine tank, not sure what we can do at this point, and whether the whole tank is in jeopardy or what.

Just looking for some advice, I hate feeling like I'm helpless and / or making these guys suffer.

Thanks in advance!!

Any way to get some good close pics of the sick fish that are left?

Post all of your water readings, including pH, ammonia, nitrite, nitrates.

What are you feeding your fish and how often? How long has this tank been up and running?
