OK - I have had my male veil tail betta for six months now - he's done very well solo in a 5g tank. I looked into his tank tonight and I saw a huge bubble nest! It is absolutely gorgeous - if I can figure out how, I'll add a photo to this post. My question is - why is he doing that?? I don't have any other bettas or fish, let alone a female! The past couple days he's spent an inordinate amount of time trying to scare me - puffing himself up at me LOL What's going on with him?? Thanks!
