Help! My bettas are bucking up and down kind of. There are many on the bottom and they can swim, but they swim up and sink a little, up and sink a little...I'm going to do a water change now. They're 12 days and have been on egg yolk, microworms, and crushed pellets. Tank is 1/2 full 10 gallon.
Could they have eaten too much? I think overeating can affect their swim bladders when they're this young. :( My best advice is PM OFL since she's bred bettas many times. I'm sorry, I've got my fingers crossed that they aren't seriously ill. *hugs*
This could be many thing, but the only thing I can come up with (as Sakura said), maybe it is the feeding. How many times do you feed them a day? Also betta pellets, even when at a fine crush are known to bloat adults so maybe you can check for bloat.
I hope everything goes back to normal. Also take into consideration that the fry could be like this temporarily. Don't think the worse. From what I've read, you have been doing a great job.
Right, BL, this kind of reminds me of Punki's Miss Piggy so that's why I wondered if it was a food issue. If it is, then you'll be happy to know that the baby betta in question made a full recovery, Green Tea.
