THE TROPICAL FISH FARM Diane Henderson enjoyed animals and shared that enjoyment with her family. Two years ago, she purchased a 30 gallon fish aquarium and some young gold fish, bottom feeders, angelfish, and a few others, for her daughter. Several months later, Diane noticed some small, brownish-colored 'bumps' on one of the aquatic plant leaves. When her husband came home they identified the 200-300 pinhead-sized bumps as fish eggs. Based on their behavior, they determined that the eggs belonged to the angelfish. Within a few hours, however, the eggs were 'gone.'
