Choco Gourami's About To Breed I Think

[Tonym]

Two of my choco gouramis have gone very protective of each other and are both guarding the same spot of the tank and seeing off the other ones if they come anywhere near where they are. They are doing something very similar to when males show agression to each other, but without the aggression. I think they may be about to breed.

Ive taken some pics so you can see what there up to. it's behaviour ive not seen mine do before.
