You aren't kidding about the price of fish food vs. human-grade food.
I had no idea. The money I could have saved!!! The SF Bay Gumdrops are
ten bucks for a 100 pack, and most of that is water and veggies. I
made my own very small "gumdrops" today out of fake crab purchased for
$2.79, and I got much, much more than 100 servings. I just put it
through a well-rinsed food processor, balled it up, and popped it into
the freezer. It turns out I didn't need gelatin to make my own food.
(Unless there is a nutritional component there that I don't know
about!) I have fed the "crab" twice today and both fish went nuts with
happiness, and NO floating. Mrs. Fish has never looked better.

I am going to do the same homemade ball thing with some "human-grade"
bay shrimp as well. I like to feed the fish some veggies, too,
lettuce, broccoli, or peas a few times a week. (Although I know lots
of people don't, it has worked well for me, especially with the
chronic floating issues.)

Do I need to add anything else to their diets, or will shrimp, "crab"
and occasional veggies be sufficient, balanced nutrition? I really do
not want to risk even the smallest amount of pellets again. It's hard
on my fish. . .and perhaps even harder on me.
