So I haven't had a betta for several years, but I just moved into my dorm room and figured I needed a roomie since I have a private room.
I went to Petco and the bettas were housed in these pitiful-looking cups. One of the bettas was even floating dead in its cup! On one of the top shelves was this rainbow-colored betta. He has some green, purple, blue, and red, so I have no idea what he is "officially."
I used flash in this picture, but his fins are more of a blue shade than green.
Even after only a day, he's a little madman. He's very active. He's been swimming all over the place and even following my finger when I wave it around his bowl. I put a betta bulb in, but it hasn't grown much yet.
I named my new buddy Charlie. He's a friendly little guy. Do you think he'll change colors at all? Isn't he pretty?
(His tail looks weird with the glass curve, but it shows a little more of the red in his tail.)
