it is a frequency thing since GF have no stomachs. they need itty bitty amounts of
food frequently. because they have a relatively short digestive tract they need
foods that are easily broken down and absorbed. GF eat mostly the critters live on
plants and algae which are high protein, high fat content but very simple fats and
proteins, not complex. land based veggies and fruits have too much cellulose for
digestion, not to mention GF dont utilize carbohydrates almost at all. so fruits and
veggies are not digested for the most part. Like peas they are good for
constipation. they do contribute to the waste load since they are mostly unused
nutrients that the bacteria must break down.
the best food is the stuff comes from the water. so find fish food with water based
protein source as first ingredient. it costs more up front, but less is needed and
there is less waste and better nutrition for the fish.
the biggest cause of floatiness is probably overfeeding.

An interesting read. I feed mine veggies quite frequently - allows a good
balance
of vitamins and minerals.
