We have three goldfish in a 10 gallon tank with filter and aerator stone. Change 30% of water each week and carbon pack once/month. One fish routinely floats "belly-up" then when we tap the tank or he is knocked by another fish, he starts swimming again. This has been going on about 1 month....

What kind of food do you feed, and how often do you feed it? Does he float worse after he eats?

We feed Tetrafin Goldfish Flakes. I guess it's worse after feeding....but it can last for several hours.

sounds like SBD...
