1 fish dead, 1 fish missing

[Coralgurl]

Woke up this morning to find my flame hawkfish completely mangled up and my royal gramma is missing. I have a couple fairly large hermits so I think they may have gotten a hold of Marvin (flame hawk). He was fine yesterday.....Not sure about the RG.....

So frustrating. Everyone else is fine.

Also missing a clownfish. Here's hoping they are just hiding.......

Had a rogue emerald crab that took out 4 masked gobies! Crabs r opportunists... Feel for ya

I had my first death in tank yesterday - a yellow tang. He was bullied to death I guess after introduction. He was in the corner for a few days, as where I found him.

I'm also missing my second banana wrasse, the first one jumped out a few weeks ago, now I can't find the other one! :|

Sorry to hear, Coralgurl!

I don't know if the hermits would catch fish and eat them. My flamehawk fish - took a hard look to figure out which fish it was as there was nothing really left of him. All his scales were gone on his body and it was very fleshy stringy bits left. But his face was intact.

Very sorry to hear of your losses.

I hate losing fish and I have no idea why or what happened. I'm hoping the RG and clown were just not quite awake yet, but it was a late start to the morning...... will take a look at things tonight when I get home.

I had a red crab at one point that I wasn't able to identify. I'm pretty sure he stayed in my 55 gl tank as there appeared to be recent moltings left in that tank when I sold the rock. I have not seen another crab since, most of the rock in my tank sat dry until I got it up and running. I did add a few additional pieces that came from other reefers. So weird.....

Unless you find your missing fish the problem is likely a lack of oxygen event that caused some of your fish to die.
Alternatively, you can be experiencing a cycle. You should check your parameters.
Alternatively, you may have had a temperature spike.

It is doubtful that anything in your tank attacked, killed and ate two fish and killed and partially ate the other in one evening.

My experience is crabs will eat dead fish or injured not moving fish.

The only other inverts fast enough to catch fish is mantis.

If you haven't added any new livestock recently then it's possible that they didn't die from a disease. It is really weird that the fish would just die overnight tho... And if your other fish are Mia that's even more unexplainable.

I have had fish for a year or 2 then slowly get more and mood skinny almost anorexic then eventually die. Recently I bought a few new fish and mysteriously they stopped then 2 days later dead. Only the new fish passed while the rest are completely fine.

Sorry for your losses!

Alternatively, you can be experiencing a cycle. You should check your parameters. Will check when I get home.
Alternatively, you may have had a temperature spike. Possible - wouldn't this affect more fish? I unplugged my heaters before I left the house this morning simply because its supposed to be fairly warm today. My tank has been hovering around 81.5 over the summer.

I did add 2 fish a few weeks ago, 2 wrasses - both are active have not been either bullied or bullies in the tank. I'll check out the tank thoroughly when I get home, testing etc. The fish were fine yesterday, I know for sure I saw the RG and clown on Monday as I was away last week and I always check for everyone. I'm don't recall seeing them yesterday, but I did see the hawkfish as he came over to the side of the tank when I was fiddling with my skimmer and overflow. He was perfectly fine and behaving normally. I should have taken a picture before I flushed him as I was shocked at how messed up he was - but any of the CUC could have gotten to him. He was floating by the top of the overflow when I saw him.

How would I check for a mantis? I had a Scott's wrasse that had a pretty messed up side, thought he scrapped himself on the rocks. I was going to catch him and put him in my sump, but he died before I could get at him. Would it be possible for a mantis to go so long without detection?
