A few weeks ago, I purchased a pretty betta, whom I names Ponzu!
I put him in a nice little 2.5 gallon tank. For the first week, he was very active and swam around quite a bit. He even built a little bubble nest the first day, but after I changed some of the water, he never re-built it!
Now though, he just kind of floats around the top of the tank, or lies on his plant. He has a great appetite still...but is much less active.
He looks pretty healthy otherwise. Fins are usually not clamped and he responds to me looking in his tank.
Is it ok that he's not that active though? It just looks so odd. He just sits motionless at the top of the tank!
