Fish The Stickleback 
of the pretty structure is a circular door. When 
finished, the nest is like a little green bubble. 
When the nest is made, the stickleback goes 
wooing, and conducts his gay wife to his home. 
She enters the nest and lays her eggs within it, and 
then flits off with no further interest in home or 
young. However, if he feels equal to a family of 
large size, he goes wooing again, until his little green 
home contains as many eggs as he thinks he can care 
for. He then stands guard by the door, and by 
constantly fanning with his pectoral fins, sets up a 
current which flows over the eggs so that they do 
not smother. He drives off all intruders by the 
most ferocious attacks, and he will be taken in the 
net rather than desert his post. 
CARE 
Since the stickleback lives in stagnant water, the 
aquarium well stocked with pond weed gives it 
fitting habitation, and it will find its food among the 
tiny creatures which naturally live among the pond 
weeds. However, it is well to feed the sticklebacks 
occasionally with earthworms cut into bits small 
enough so that they may be swallowed. Small 
meal worms also may be given. The glass pipette 
must be used to remove from the aquarium the 
remains of the food.
