BELPT'S AQUARIUM, ST. LOUIS 5 
COLLECTION No. 5 
The gold helleri or swordtail grows simi¬ 
lar in size to the well known Mexican Sword¬ 
tail. It differs in color only. No. 2 and 
No. 4 show the variations in colors of the 
Betta from Cambodia (Cambodia is a small 
state near Siam in China). No. 3, the blood 
red moon is well known and is a live bearer, 
the same as the gold helleri. No. 5, Pearl 
danio, scientifically known as the Brachy- 
danio albolineatus, more commonly known 
as the Mother of Pearl fish, is a native of 
India, very hardy and an egglayer. All of 
these species are ideal community tank fish 
and peaceful. Two Betta males however can 
not be kept in the same tank. They are also 
known as Siamese Fighting Fish.

NEW FANCY COLORED 
VARIATUS 
A New Creation Introduced By Us in 1935 
The red males vary in colors and designs like 
the original variatus. The most remarkable thing 
about the black variatus No. 49, is the fact that 
they breed 100 per cent true with only minor 
color variations. It is the only fish known where 
all of the male babies are born black and the fe¬ 
males white, and also the only fish on which the 
sexes may be distinguished at birth. As most live 
bearing red colored tropicals are fairly delicate, 
the red variatus is hardy and able to stand tem¬ 
porary temperatures of 45° F.

things to say about your fish that I would like to have 
your catalog. C. P. Bange, 88 Chenery Street.
