Just a quick question my new betta is in constant "fighting pose" where his fins are erect and his gils are puffed (I cant describe it very well) I know they do this sometimes but he seems to be doing pretty close to every 2 seconds I put a background on the tank to cut reflections and there is plenty of plants does anyone know why he is always doing this?

I have a betta that does this all the time when I move him into a new tank. He's just establishing new territory I think. I would keep the lights off (or dim) where the tank is and give him a day or two to adjust.

How new is he?
