Shani has SBD for the third time this week. I fast her for three-four days, then I feed her a TINY bit, and she's got it again! What am I do wrong?! The only thing odd I'm noticing about her right now, besides being unable to leave the surface, is she's eating the bubbles on her tank...? I just gave her a one hundred percent water change, so she's going after the tiny bubbles on the tank walls. This looks like it's the worst she's gotten it. She's not bloated at all, and she's actually pooping right at the moment. I'm so confused. Only one of my other betta got SBD, and he passed away soon after.
