Part II: Fish and How to Care for Them
Microworms
Microworms (Anguillula silusiae) are non-parasitic worms that float freely in
water. These worms reproduce in a matter of days.
You can easily culture microworms at home, and they make a good starter food
for young fry because of their tiny size. All you need to do is mix a little oatmeal,
yeast, and water in a bowl until it forms a paste. Add a small amount of
microworms to the paste from an existing culture (which you can purchase on
the Internet) and allow it to stand at room temperature for a couple of days.
When worms appear on the sides of the bowl, transfer them to the fry tank.
Liquid, powdered, and growth foods
You can purchase manufactured liquid fry food that comes in a tube that
resembles toothpaste. Use this product sparingly because it can foul the water.
Powdered food is used to feed newborn fish. The powder is too small to be
used as feed for adult fish, and will end up fouling your tank if not used for
baby fry.
Fish food manufacturers make a wide variety of foods to match the growth
stages of your young fish. Hikari makes a wonderful line of baby fish foods
which are made to fit the growth stages of fish.
Read the labels carefully to choose the correct product for the age of your
developing fry if purchasing from a pet store.
