Sounds like a lot of your critters are sexually frustrated
I suppose you could let the beardies have their fun (if Jamie was willing, that is) and then just don't incubate the eggs (reptile birth control is fairly easy, compared to, say, cats and dogs) -- like put the eggs in the freezer or something. Although I admit that I would feel bad about doing that myself. Sounds like you have a regular circus going on around there. It must be fun to watch, at least.
Puff didn't show symptoms of mating season for the last several years of his life. I guess he just wasn't healthy enough because I've heard that normally they don't lose interest when they get older. He'd do the head bobbing and
black bearding at odd times of the year when he was younger -- didn't seem to have anything to do with the seasons. Often it was in the middle of the winter and I wondered if his biological clock was set for the southern hemisphere, or maybe it was because the winters here are so long. We didn't want him to mate because like you, we didn't have the money or the time to take care of a bunch of little beardies. He also had adenovirus and we didn't want to spread that around, especially since the babies can apparently get it from their parents.
Did Jamie used to have adenovirus? I didn't know that it could "go away." I thought that once they had it, they had it for life, unless they've found a cure. That would be awesome if they did. We never tested Puff more than once. The assumption was "once positive, always positive," and we figured that was what was causing all of the health problems he had over the years.
I wonder if some bettas just have a natural tendency to bite their tails more than others -- maybe genetic or something. It sounds like you're doing everything possible to keep him from getting bored, short of getting him a girlfriend. Bubble nests, huh? That's a new one on me -- I suppose it's a good way to tell if they're thinking about making little bettas.
Nothing much new around here otherwise, except that our house seems to be trying to fall apart. Working on the windows and now it's the back door. We can barely get it open and if we do, we run the risk of not being able to get it closed and locked again, and locked doors are a must in this neighborhood, especially lately. I've been trying to tell my husband that it might be "snow load" on the roof, but he's got to find a way to stand on the ground and get it off with a rake on a long pole or something. No way is he going up there. I'm a stickler about his safety.
It's slowly and steadily getting "warmer" -- highs in the 30s and 40s most days now. "Breakup" to look forward in a month or so -- several weeks of mud and slush. Pretty ugly but we Alaskans love it because it means summer is just around the corner. We have to enjoy our summers while they last because they're really don't-blink-or-you'll-miss-it short.
Lately I find myself missing Puff maybe even a little more than I did right after he died. Go figure. Sometimes I still hear a noise that sounds like it came from where his tank used to be and for a moment I think it's him. Then I remember that he's not there anymore. Maybe his spirit comes to visit once in a while?
Another TLDR. Sorry about that. Congratulations if you've read this far
