What do baby catfish look like?
Baby guppies are very small. Most are around 1/8" long when
born. They are nearly clear with a silver color in their bellies.
Some color foms of guppies will have babies that exhibit a limited
amount of color at the time they are born. Most commonly this is
seen in red verieties. All varieties will begin to "color up" or
get thier adult coloration in about week 4-5.
