If so, what kinds are best?



When I called an online fish dealer yesterday asking about fancy
goldfish, I was offered the following two tidbits of info: 1) if one is
using pelleted food, reconstitute the pellets in a little (aquarium)
water before feeding; apparently this helps avoid some fin-related
problem associated with dry food expanding in their stomachs, and 2)
occasionally feed them small amounts of vegetable matter, such as a
frozen pea with the skin peeled off or a little bit of lettuce. I tried
reconstituting the pellets I have and the only real problem I can see is
that they get a little mushy and it's a little harder to gauge how much
their eating. Then again, the idea of feeding goldfish "as much as
they'll eat in a minute or two" seems to me to come from people who've
never kept goldfish before. None of the four I've had so far goes into a
constant feeding frenzy when food is added. They let some pellets drop,
grab at a couple, and then take their time cleaning up the rest.
