I tend to agree with what Kim said in another post about this tank - if the jags were a pair, the jag would be trying to bully the other fish. If the list below is all in one tank, it is going to be interesting long term.
1st fish looks more like a Trimac than a Flower horn to me, as for the Gt i think is a Male,
i'm thinking that both Jags are females u can see one of them has their tubes hanging ready to lay eggs.
