So I bought a cute little female dumbo betta a while back. The more I watch her the less I’m convinced it’s a “her”. The betta in question has an egg spot, but also longer fins. I’ve also noticed that it had a beard. I was beginning to think that this she might be a he so I decided to try and breed him with one of my females from my sorority tank. He started dancing and flaring, but he never build a bubble nest, despite the bubble wrap I put in the tank and he actually started to hide from the female, who by the way was SUPER into him... so... what is he/she????
