Hi friends! I found this VT Betta at PetCo. He was pretty beaten up from having poor water conditions and living in a tiny bowl. I decided to rescue him. After a week this is what he looks like. Thanks to everyone who is on this forum, I was able to get the information needed to save him! His name is Harry, my four year old nephew named him this because he looked hairy and didn't have a butt-hole. So I went along with it. Here's Harry and thanks for the all the useful info!
Yeah, me too. I was worried because his lower fins looked awful. As you can see in the picture a good portion was missing, between the lower fins and the tail, there was nothing there but his body. Today it looks like its growing back. It's incredible what a week and clean water can do.
