For those with fish battling SBD, this isn't a surefire method but this is something I accidentally discovered. I had a Tetra algae wafer in my Betta tank for my snail. My female Betta has recurring Swim Bladder Disorder for no apparent reason, it must be genetic. Anyway before I could remove the wafer from the tank she ate a little of the soaked morsel and maybe it's because of the plant matter in it, but it goes through the fish's system EXTREMELY fast and makes them poop a ton. It's not a good complete diet for a fish, but if my girl's SBD symptoms last a while I'll give her a tiny bit of soaked wafer and it clears out her system when peas prove ineffective. I don't even use them for my snails anymore, just Azzie!
