I have been keeping bettas for a couple years, not professionally or anything too crazy. I came across this little guy at petco who was being sold as a “white opal male” however it seems the fish has an ovipositor. It does seem to be a younger fish considering it is barely an inch if not less. I can only see the little bump when the pelvic fins are flared. The pelvic fins are a bit thicker as well. You have to zoom in to see the potential ovipositor on the photos below. Trying to decide on a name lol. Any pointers help!
