I just got a new betta yesterday, to replace one that had just passed on. He was the only one that a color pattern that caught my eye. What I am concerned about is that he always holds his tail fins kind of bunched up and doesn't seem like he has a very long tail. A beautiful blue and red pattern when he does hold his tail out and open. Is he maybe young and hasn't developed his fins completely? Or stressed by being put into a new home? BTW, he is in a 5 gallon office tank with plants and decorations. Swims a lot and comes to the front of the tank, seems pretty social for being a new pet. Can't do pics till I get minutes for my phone. Previous betta was a nice blue veiltail-Sapphire- I do miss him. Maybe in a few days, my new little boy will look better.
