A few weeks ago, I got this little guy from my LFS. He was really tiny, skinny, and had pretty extensive fin rot. Even in this sorry state, sitting in his little 5oz cup, I saw something in his face that made me take him home that night. Here's what he looked like then:
I got him home, fixed up one of my roomy 32oz cups for him with some plants and AQ salt, plopped him in, and fed him. But, once he saw those whiteworms, he went nuts! It was a few days before he would eat anything that wasn't wiggly, but now he's a bloodworm eating machine.
Most of the "Halfmoon" bettas my LFS gets in are actually deltas, but this guy has a perfect 180* spread. His fins haven't grown back yet but he's colored up and loves flare time.
Here's him 2-3 days later:
And here is him tonight:
Please excuse the IAL stained water. I keep all my containers that dark, but it makes taking photos kinda hard. His markings are actually steel blue. =D
