1 fish dead, 1 fish missing

I highly doubt your hermits did this.

Sometimes crap happens that can kill fish. I don't know your system or your habits, but it's usually tank owner caused.

Hate to say missing = dead 99.9% of the time.

Better test your water. Do a water change.

Ammonia is 0 on salifert test. It's at 1 on the API test. Water is mixing, will do a change in an hour or so.

The royal gramma came out 5 mins ago so it's just the clown and hawkfish.

I've had an issue with my skimmer, had a snail caught in the intake. I took it apart, cleaned it but it wouldn't stop over flowing, so I left the plug out and just let it run. It finally stopped last night. I do use filter socks and kept them on during this time. Checked the flow on the return pump, it was reduced, the intake was clogged with cheato, cleaned off and it's running fine.

Last water change was 2 weeks ago before I left on holidays. Tank was looked after while I was away, as the weather was cool, was not worried about the temps. Top ups done and fish were fed.

I'm not sure what I could have done or not done to cause these deaths

I have lost a few smaller fish in the past year and it was not until I turned off all the power and started using a flashlight the last time that I found the remains of one in the powerhead ... since then I have seen a couple of the smaller ones swimming into the chamber of the powerhead while it was off-cycle and I have begun to wonder if I have depressed (or potentially hard-of-thinking) fish ...
