OK, one of our Bettas, Andrew, seems a bit prone to constipation.
When we first got him, we were not aware that too much bloodworm bungs up Betta's guts. Anyway, we got him well and truly blocked up with bloodworm. He didn't eat for about 5 days, and eventually it all cleared, and he has been fine for the 2 months since on a diet of Hikari Bio gold mostly, with occasional pea, frozen daphnia, brine shrimp and bloodworm (bloodworm no more than once a week).
So, this last saturday it was his bloodworm day, and I gave him 3 bloodworms, with apparently no problems. The next day, on sunday, he had a small piece of pea (no shell) and a couple of pellets.
A few hours later he developed what I'm assuming was a swim bladder problem caused by gut blockage. His abdomen was clearly bloated and he was much too buoyant, and strugglinig to swim downwards at all.
So, today, about 18 hours later, his swim bladder function seems back to normal and he seems fine.
My initial thoughts are that it was the bloodworm on saturday that caused the blockage which manifested on sunday. Or was it the pea on sunday that caused the problem ? What are your thoughts ?
On my current hunch, I will drop the bloodworm completely, and still give him pea once a week. However, if I'm wrong, and it was the pea that was the problem then I could cause him further problems by doing that. Would like a little moral support in my decision-making on this one.
