SPOTTED MOLLIENISIA (Black Spotted 
Mollienisia). In breeding types of the Black 
Mollienisia some fish remain “spotted” longer 
than others; a certain per cent never turning 
entirely “black.” The purchase of a few pairs 
of these Spotted Mollies affords an excellent 
opportunity to develop some valuable all-black 
specimens, at a very modest cost, when these 
fish mature. 
MOSQUITO FISH (Heterandria formosa) are 
great destroyers of misquitos and sometimes 
bear the name Mosquito Fish, also. They are 
among the tiniest of the known vertebrates, the 
females seldom exceeding one inch in body 
length, the males about three-fourths of an inch 
at their largest.

EGG-LAYING VARIETIES 
THE CICHLIDS 
ANGEL FISH or SCALARE (Pterophyllum 
scalare): This aristocrat of the pygmies is a 
native of South American rivers and is char¬ 
acterized by a grave and dignified bearing. It 
is sometimes called the fresh-water Angel Fish. 
The ground color is silver touched with yellow, 
and its name scalare (from scalaris, a ladder) 
comes from the strong, even banding of body 
and fins. Half-Moons, a name derived from the 
Their 
shapes of the fins, subsist on small floating 
plants, Daphniae and prepared fish foods.

THE CHARACIN FISHES 
TETRA VON RIO (Hyphessobrycon flarn- 
meus) is one of a species of Toy Tropical Fishes 
which shows such numerous variations that 
they have puzzled ichthyologists attempting to 
classify them. Natives of Mexican and Central 
American waters, little is as yet known of their 
habits. Even the number of scales and fin rays 
vary greatly in different varieties, and other 
singular changes occur with age, sex, season, 
food and water temperatures. All of them are 
distinguished, however, by a unique adipose fin, 
a tiny additional dorsal fin near the tail, which 
is always present. 
TETRA VON BUENOS AIRES ( Hemigram - 
mus caudovitatus ) is another of the Tetras, of a 
greenish color with red fins. 
COPPER SPOT TETRA (Hemigrammus ocel- 
lifer) is distinguished by a copper spot at the 
base of the spine. 
The SILVER TETRA (Ctenobrycon spilurus) 
is a hardy species, native to the rivers of Dutch 
Guiana, Paraguay, the Amazon River and other 
balanced Goldfish tanks and in all Tropical 
tanks. 
Scavengers should be introduced into every 
Aquarium. Snails are particularly useful in 
( keeping the water and glass clear. They will 
II also help to keep any fish food that may have 
( fallen on the bottom cleaned up. 
I Should the water tend to become green, cut 
down the amount of direct light or sunlight 
n the Aquarium gets each day. Very often a 
green condition will clear up of its own accord 
. in a few days. This is the most desirable way 
to get rid of it, as it is likely to be a consider- 
c able period before that Aquarium will again 
' become green; whereas those tanks cleared 
; chemically or by flooding soon become green 
FEEDING—This is an important matter for 
all types of fish kept in the Aquarium. We list 
several fish foods (see page 30), all tested by 
us and used for feeding our own stock. We 
suggest their use. Feed Goldfish every other 
day about as much as they will take in five 
minutes. If you would keep Goldfish in good 
condition, feed sparingly. 
Feed adult Tropical Fish once a day about 
as much as they will eat in ten minutes. Avoid 
excess. Baby Tropicals should be fed two or 
three times a day. For the former, use our 
Tropic Food No. 1, for the young fish our 
Tropic Food No. 2. (See page 30.) 
Be sure to remove all food that settles to the 
bottom of the Aquarium, as this decaying food 
will sour the water. 
Habits in Pools and Aquariums 
South American waters, and is an ideal aqua¬ 
rium fish. The young sometimes number 500 
at a single spawning, and make rapid growth 
after the first two weeks. Both sexes have a 
golden iris flecked with red, and an iridescent 
body marked with blue. 
PRISTELLA (Pristella riddlei), native to the 
waters of British Guiana and some other South 
American rivers, has a short, deep body and is 
of variable coloration. The young of Pris¬ 
tella are rather difficult to rear in aquariums, 
surviving only in quite shallow water. 
BLOOD FIN (Aphyocharax rubripinnis) has 
silvery pearl scales and blood red fins.

THE CYPRINODONTIDAE 
The Cyprinodont pygmies are principally de¬ 
rived from natives of India and Africa, and 
present many variations as they are produced 
for the pleasure of the home aquarium or gar¬ 
den pool. 
GOLDEN FUNDULUS (Fundulus Chrysotis). 
A beautiful native tropical-color tones, a warm 
olive green overlaid with irregular, iridescent, 
golden spots. 
FUNDULUS NOTTI (Florida Zelua Fish). A 
most desirable aquarium fish native to our 
Southeastern states. Hardy and of mild tem¬ 
perament. 
FUNDULUS HETEROCLITUS—One of our 
most popular native killifishes suitable for 
aquarium use. Very hardy; easy to keep. A 
beautiful iridescent body with alternating light 
and dark bands. 
MEDEKA ( Orizias latipes). A hardy, peace¬ 
able semi-tropical fish with golden, almost 
transparent, body. One of the easiest of the 
egg laying fishes to breed. Will take any pre- 
pared food.

DANIOS are among the favorite aquarium 
fishes of the Toy Tropicals, occurring in several 
well marked varieties. 
The SPOTTED DANIO (Brachydanio Anali- 
punctatus). More strikingly attractive than 
the rerio and just as hardy. Two dark blue 
stripes separated by a golden line running the 
entire length of the body. Numerous dark blue 
dots cover the lower body and fins. The so- 
called ZEBRA FISH (Brachydanio Rerio) gets 
its popular name from its zebra-like stripings 
extending from the gills through the caudal or 
tail fins. It is the smallest of the Danios, aver¬ 
aging about one and one-half inches in body 
length. Danio Malabaricus, often called the 
GIANT DANIO, is the largest of the variety, 
often attaining a length of three inches. It is 
considered by most aquarists the most beautiful 
of the Danios, having a blue body with lateral 
stripes of salmon-yellow. Diano albolineatus, 
popularly called the PEARL DANIO, is a beauti¬ 
ful aquarium species of this variety with irides¬ 
cent mother of pearl and opal coloration. 
THE BARBS, like many other varieties of Toy 
Tropical Fishes, occur in several species, the fry 
of all of which are quite easily reared in the 
aquarium. The variety is native to the waters 
of India. The Barbs live peacefully among 
themselves and with other fish. The ROSY 
BARB (Barbus Conchonius) is largest of the 
Barbs, all of which are distinguished by their 
large scales. Barbus Oligolepis with red and 
silver markings and fins bordered with black 
is so iridescent that it is sometimes called the 
IRIDESCENT BARB, though variations in 
its coloring are toward gray-greens and grass- 
greens, so that it is sometimes called the Green 
Barb, also Barbus Semifasciolatus. STRIPED 
BARB is a striped member of this variety.
