MARINE AQUARIA 
Pisces. Of the Marine fishes only those forms will be mentioned 
which are readily obtainable, the native Eastern and Mi§ddle States 
coast species, and strays of the Gulf Stream, which may survive in the 
marine aquarium. These are: 
Herrings or Clupeide. ‘These fishes are distributed throughout the 
whole of the North Atlantic, and the young make interesting aquaria in- 
mates. ‘They may be obtained in abundance along the shore in summer. 
Of these the Common Herring, Clupea harengus, the Sardine, Sardinella, 
and the Menhaden, Brevoortia tyrannus, are the most numerous forms. 
Toothed Minnows or Pecilitde occur in brackish water near the mouths 
of rivers and along the coast. They are all small fishes varying in the 
adult from 2 to 6 inches. The most common forms are Pursy Minnow, 
Cyprinodon variegatus; the Kallifish, Fundulus heteroclitus ; the May Fish, 
fF’. mgalis; and the Rainwater Fish, Lucania parva. All are very hardy 
and will survive in the aquarium. 
Sea-horses or Hippocampida. The strange shape and interesting habits 
of these fishes make them very desirable aquarium inmates which survive 
for long periods. The abundant form on the Atlantic coast 1s Hippocam- 
pus hudsonius, very similar in appearance to H. hippocampus of Europe. 
Pipe-Fishes or Syngnathide. These fishes are closely related to the 
Sea-horses and are found everywhere on the Atlantic coast. The head is 
small and the body elongated, somewhat resembling the eel. The com- 
mon form is Siphostoma fuscum, a most interesting aquarium fish. 
Sticklebacks or Gasterosteide. These interesting nest-builders have 
three salt and brackish water species which thrive in the aquarium. ‘These 
are the four-spined Stickleback, 4peltes quadracus; the ten-spined Stickle- 
back, Pygosteus pungitius, which also inhabits fresh water, and the Two- 
spined Stickleback, Gasterosteus bispinosus. Schools of them may some- 
times be encountered in midsummer in bays and brackish water estuaries. 
Their habits are described on page 72. 
Silver-Sides or Atherinide. These small carnivorous fishes are found 
in numbers near the shore in brackish water and at the mouths of rivers. 
They resemble the smelt. Two species occur on the Middle Atlantic 
coast, Menidia cerea and M. notata, known as the Sand Smelt and the 
White Bait. 
Mullets or Mugilide. The young of this genus will survive in the 
aquarium. Theadults reach a size of 2 feet and over. The most numer- 
ous marine forms are the Grey Mullets, Mugil cephalus and M. curema, 
both numerous in salt and brackish water during the summer. 
Crevalles or Carangide. The young of three species of these fish are 
abundant during the summer months along almost the entire Middle
