I haven't decided what to call him yet, but he's going to be living in a 1 gal tank, heated, with a few live plants and a betta log until I rehome Brutus with my coworker. Then, he'll move to that 2 gal tank.
Here are some good pics! I wasn't 100% sure what his color would be as the water in the betta cups was so blue (I think there had been too much of whatever chemical they use added, as all the bettas were showing stress stripes from it), but I think he is a copper after all like I was assuming. Right now he's kind of pale from stress, and has some stress stripes showing. You can see his horizontal stripes in the pics in the new tank.
Had him floating in the dwarf puffer tank at my boyfriends to keep his water at a stable temperature until I got him. He and the puffers were quite curious about each other lol.
I have a few more I'll post here in a bit. Photobucket it taking forever!
