SBD= Swim Blader Disorder. Dessa yngel kommer inte att repa sig, lika bra att avliva dem på en gång. Jag har själv haft ca 6 yngel i senaste kullen som uppvisat dett beteende. Hittade en underbar sida på nätet:

Ett utdrag vilket försöker ge en bra förklaring till SBD:
"There has been some speculation about Swim Bladder Disorder and the overfeeding of brine shrimp. Personally, I believe that overfeeding of any protein-rich food like BBS will set you up for swim bladder problems in young bettas, so remember that moderation is the key. Each fry will be fine eating 3-5 shrimp per meal during their first month, so watch carefully how much you're putting in that tank. Fry gorging on BBS until they are about to burst may look cute, but its not very practical. In addition, uneaten shrimp will die quickly and pollute the water. I always rinse my sieve with the shrimp into a clear cup of water and feed them with a dropper. This way I can more easily control how much BBS is going into each tank, and adjust accordingly. I also alternate feedings of BBS with other foods, and I've had very few cases of swim bladder disorder"
