Recently my first betta fish Mr. Badfish died, so I spent some time studying more on bettas and purchased my boy Poseidon two days later.
When I first bought Poseidon, his color was dull and he seemed tiny. He was curious though and I fell in love.
Since his first day, he appears to have gotten bigger (though that might just be his fins looking fuller c: ) and he has quite an attitude! Last night I caught him flaring for the first time.

He knew I was taking pictures and he wouldn't stay still. Usually he floats near the front and shows off until I look at him. He also follows my finger. (: He's much more active than Mr. Badfish was.

Zoomin around.~
The next week I went to Petco (they don't really take good care of their fish) just to see what types they had. I realized they had about three females. One had a bad case of fin rot and was looking rough so I told one of the workers and he took her away.
Then I saw this pitiful tiny white female CT. I saw some blue on her fins and she looked like she had potential so I bought her and another tank.
She was pretty limp though she'd zoom around like she was frightened.
We named her Noodle.
I took her home and set her up, and she's since gained color. I also notice little blue spots on her body. I'm not sure what those red stripes are, but they were on her gills when I bought her and remain. It's her second day home and I can't get her to eat, though if I walk away and there's a pellet around she'll nip at it.

Here she is zoomin up.

Investigatin' some rocks.
Sorry for the wall of text and such. I'm just majorly in love with my bettas. :3
