Siamese Fighter Question

I brought a Siamese Fighting fish home today, placed him in a community tank
with some Neon Tetras & Zebra Danios. Since putting him in the tank I have
noticed that he regularly flares out his gills, or something around that
area, seemingly when he's looking towards the glass. I know that these guys
fight others of their kind & display in a similar way when a mirror is put
against the aquarium, so I assume this is part of his display. Will him
doing this almost constantly cause any problems? ie tire him out? I have
taken a couple of pictures of his display, but need to find the cable to
connect the camera to the computer. I'll post a picture to alt.binaries as
soon as I find it.
