TROPICAL AQUARIUM FISHES 79 
THE SUCKER 
As a novelty the Sucker may be kept in an aquarium. It is by no 
means a handsome fish, appearing somewhat awkward and clumsy. Pre- 
ferring vegetable foods, it will also take earthworms. In habits it is 
perfectly harmless.

THE ROACH, OR SHINER 
Here we again have one of the very hardy small aquarium fishes. 
It is decidedly active, and if kept in a bright light shows its brilliant 
silvery sides to advantage. The Roach is seldom still and has a stimulat- 
ing effect upon the more lethargic members of a general collection. It 
is of a gentle nature and is not at all particular as to what it is fed.

THE CHUB 
Not usually known as an aquarium fish the Chub, in the smaller 
sizes, does very well and may be kept with other fishes whether small or 
large. It is a nest-builder, but requires a much larger space than is to 
be thought of in an ordinary aquarium. The Horned Dace, or Creek- 
Chub, is the most lively, and is the best species for the aquarium. Chubs 
are vegetarians, thriving on boiled cereals or white wafer food.
