Banggai Fish acting weird

[Badiskm1]

I have a 300 liter/80 gallon tank with 2 ocellaris clowns, 3 banggais, 1 sand shifting seastar and 1 one spot foxface. I came back from school, and one of the banggais was laying down on the sand I thought he was dead, so i tried to pick him/her up but him/her moved, but he/she is not moving as fast and isnt moving a lot, i think the two things:
1. he/she got stung by the foxface
2. this might be behavior of pregnancy or brooding
If you know about this or have had experience, please help me, as I am worried that he/she might die, thank you.

Three Banggai is not going to be stable in an 80 gallon tank. A male plus female will work, but two males will not and a FMF will work only in large tanks.

One of my Banggai disappeared, I really don't know what could have happened. I took all the rock out and he was no where. Im guessing the other fish ate him.

More likely that the other banggais killed it and your cleanup crew disposed of the remains.

Sorry, I know that stinks, but Steve is right. These fish do not do well in groups. Keep a sharp eye on the other two and be prepared to remove one. Unless they're a male and female, the strongest may pick off the weakest so you only have one.
