I bought a betta on Friday and he seemed very happy. He likes to swim but also hang out towards the bottom. I was going to bed today and saw he made a little nook in the gravel in the bottom of the aquarium. ( the aquarium has a little dip in it to put gravel). He is in between gravel and the glass. I just want to know if I should be worried he is sick? This is my 1st fish.
Oh, he looks fine and no appetite change. I also treated the water he is in right now. He gets flake food once a day and there is no heater on the tank.
