I have never had a Betta do what Bubbles does. He is happier than can be and he has a rather unique personality. He sees me even walk into the same room he follows me like crazy... so if i sit down he will stay in one spot and watch me for I would swear about 3 minutes, swim around and repeat. Odd thing is when I'm around is the only time he builds his bubble nest.
My question is about one odd behavior. I have the glass rocks covering the bottom of his tank and they are a light tan/brown color. He goes head first down to them and acts like he is mating with it (hugging) then swims up and blows a bubble.
I've had plenty of Betta's before but I've never had them do that. I'm not to worried I just think it is kind of on the odd side.
(He is in a 5 gallon tank atm all on his own and PH and other such levels are perfect, including temp.)
