The problem is my pop-eye fantail. Man, does she get floaty. I've read
elsewhere that this is common. She has grown a lot in the last year,
and has the nice wide bodied, egg-shape. But the second I give her ANY
sinking pellet food, she floats like crazy. I have used Hikari,
BioBlend, and even recently tried Pro Gold. And soaking doesn't help!

I have the exact same problem with my oranda - he floats for hours after I feed
him soaked ProGold pellets. I hate seeing him try to swim around normally and
just shooting back up to the surface. I've heard pinching the pellets after
soaking can help eliminate floatiness (gets rid of air), but I haven't tried
it. I also feed them peas - no visible effect, he still floats after feeding.

Feel free to share if you come up with a solution!
