Gourami Help

[Mollygirls]

At least I think its a he!!! I have 2 powder blue, a honey and a fire red... However the one blue one (named finny for his lack of fin when I bought him) is hiding under one of my ornaments and wont come out for the past few days.. No one bothers him but if the other blue gourami even comes close he will "smack" him with his tail to get him away.. Is it just territorial? I think the red and honey are both girls.. The blue are both boys.. If that is helpful to know..

Thanks
