Well, I ended up going out and getting my first fish over the weekend. He is a very handsome blue and black bicolor betta who I have named Oranos.
He was kept in such a terrible condition in the pet store, but he seemed to be the most active of the bettas they have and I love his dark colors. He has actually become noticeably more colorful since I put him in his new 1.5 gallon tank from Walmart with a filter and a heater. I would have liked a bigger tank, but then I couldn't have afforded a heater or decorations. As for decorations, I got him a fake plant and a little cave decoration for him to hide in.
So far he's been a bit erratic in behavior, I'm not sure if he sees his reflection or not, but he sometimes randomly darts around and flares up but then calms down a little bit later. Maybe he's just getting adjusted to his new home.
I will hopefully have pictures of Oranos to post tomorrow!
