Feeding Rings. Many aquarists prefer training their fishes to look 

 for their food at a certain place in the aquarium. One way of doing 

 this is by use of a feeding ring, in which floating food is placed. It 

 has the advantage of confining the food to one spot, and that when it 

 sinks it can be over a cleared space where it will easily be found. 

 Telescopic-eyed goldfishes are nearsighted, and a feeding ring helps 

 them locate the food. It must in truth be said that such fishes find 

 their food largely by the sense of smell, and that they will, in nearly all 

 cases, eventually locate it, but they come to it with more certainty, 

 having once learned the use of the ring.

The illustrated subject is three inches in diameter, and is made 

 of bent glass tubing. Sold by the dealers in aquarium specialties. 

 They may be made from a piece of cork, with a large hole cut in the 

 centre. After the cork becomes partially water-logged one can sow 

 grass seeds on it. When the grass has become about an inch high 

 the cork is turned upside down so the fish can enjoy themselves 

 nibbling it off.
