I love it when my bettas make nests! My female VT, Annie, made a bubblenest in my community tank this morning. But she ate it because I took a picture of it! lol!
Males are more known for making bubblenests due to the fact that they build them when they are breeding. But female bettas are capable of making bubblenests.
Sometimes, in place of the male, breeders leave the females with the fry when breeding them. This is not a very common method, but it is possible.
i cna wait to breed them! i was thinking of naming him something related to 'bid' (a.k.a- Blessing In Disguise, because i thought he would be a wast of money, but i guess not!)
