Yeah, I was looking at that after I posted the pics and you might be right. I had gone back and edited the comment before I saw your post. They do label deltas as halfmoons though. I see them there all the time. I purchased this one when they first started to stock the "higher" end bettas a few years back. Now all I see are deltas labeled halfmoons, but I keep looking...lol. I occasionally come across a prize at that store and even though I'm not looking for anymore bettas...I still look
This one has some nice curly fins...yeah. When I was really into bettas I had heard that curled fins were considered a flaw. I like it !
