Well dang!!

Bought 2 bangai last week, came home today and didnt see one. All my inverts are currently eating him . This is the first tragedy since setting up my tank. This is upsetting, the worst part is...they were bought for my girlfriend and she loves them. She'll be home in 15 minutes

Sorry to hear about your loss. How long has the tank been set up and cycled? Are there any visible signs of illness on the remaining fish? Spots? Red streaks? etc. Are they eating?

I'm sure you did so already, but if not, remove the dead fish. Your GF does not need to see the CUC doing their job on her fish and if it's a new tank, you don't want an ammonia spike.

Water went in november 1st, was done cycling December 7th. Parameters are where they should be. The last 2 days one of the bangai was acting funny, wouldn't eat and that made me nervous. Tried 6 different varieties and nothing would give. He also never paired or really got close to the other bangai. Last night he was in the corner and by himself all night, samething this morning . I tried target feeding and he wouldn't eat. I thought something was up but didn't know what to do except monitor the fish, came home from work today and literally bring torn apart by my emerald crab, and my hermits.

I had a bangaii cardinal and it never ate or stick with other fish. Some fish aren’t used to aquariums, I guess.

If two males, may have fought as they typically do.

That's tough. So sorry.
If the tank did not experience an ammonia spike when the fish were added, my guess is they came in with a pathogen of some type. It's very common for bugs to hide in the gills and intestinal tracts of fish. Check out these threads on quarantine and/or treatment from two experts I trust here with my fish, and hopefully the information learned will help you decide on next steps.

Some fish - discus and chromis and many others do not do as well as a pair - alone - when first added to a tank - unless for example you bought them from a place where they were a pair to start. If not - its best to start with 'several' so that there is not one that is constantly picked on..

That said - Many times these 'schools' are whittled down to a pair of fish - depending on the size of the tank - and the number of fish

THAT said - as everyone else has - is there any evidence that other fish are sick, parameters our out of whack, etc...

THAT SAID: Sorry that you and your GF have to go through a dead fish

Thanks for responses everyone. They were not paired when I bought them, was hoping they would pair up as our clowns did. Water is completely fine all parameters in check. Did a 15% water change tonight and added a couple more corals. First death is the toughest but definitely not killing our spirits for reefing...If anything it encourages us and me specifically to do further research and continue to learn from this great hobby!

Everyone else in the tank is extremely happy thriving and growing . They had more bangai at the LFS tonight, instead of replacing it we both decided to go with a royal gramma in its place. They didn't have any in so we will pick him up in a couple days .

The hardest thing to resist is to quickly stock an empty or near empty tank. Though I'm sure it's not what you want to hear, my advice is to wait on adding any new fish until you are sure a killer pathogen has not already been introduced. You do not know at this point what killed your fish. It could have been shock from a too quick acclimation, disease, an ammonia spike, or a pathogen that came in on the fish, just to name a few things. The debate to quarantine, not quarantine, or prophylacticly treat new arrivals is a long standing debate here at R2R. Many reefers are passionate about what they believe is the right way to introduce fish to a tank. Both sides of the debate have valid arguments. While you're waiting for the new fish to come in, please read through the many threads in the "Fish Disease Treatment and Diagnosis" forum and educate yourself about the different philosophies, saltwater practices, and fish diseases. Make next step decisions based on your research. You'll soon learn who the experts are in the different saltwater practices and put your trust in their advice. Good luck. I hope everything works out with the tank!
