The order Tetraodontiformes contains Porcupinefish, Triggerfish, Boxfish
and the Pufferfish are almost entirely found in the tropics and subtropics.
Only a small amount are found in fresh and brackish water and they all
belong to the pufferfish family. One of the more common of the "rare
fish" The Green puffer needs special care and should only be kept by
the more advanced hobbyist. This fish is usually wrongly named Tetraodon

Green Puffer, Puffer.
Tropical Eastern Asia, from then coastal regions of Indochina and the
Philippines to India. Found in fresh and brackish waters.
General Body Form:
Very thick set and shaped like a blunt club. They have protruding eyes
and a very broad forehead. The Caudal fin is fan shaped and there are
no Ventral fins. The body is somewhat covered with small spines and
the skin has a leathery texture.
The color is variable depending on age and the origin of the fish. In
mature specimens the top and head area is marked with large Brown or
Black spots. The spots on the side are smaller and also round in shape.
The body color between the spots is a beautiful Emerald Green color
which makes a nice contrast to the dark spots. The bright Green color
is subdued in younger specimens. The fins are semi transparent with
a slight Yellow tint to them.
The most recognizable trait of the Puffer is its' ability to inflate
a sac like area of the gut with water or air to inflate themselves into
the shape of a ball. Most puffers are undemanding in their care and
many of the Brackish species can be acclimated to hard, alkaline water
fresh water. Tetraodon nigroviridis is one of these species. They are
not hard to feed and usually will accept all types of flake, frozen
and live food. In the wild they feed on small mollusks and invertebrates.
The Green puffer will come to recognize its owner and will get excited
when you approach. The tank setup should contain plants and rockwork
for hiding as well as open areas for swimming. They are best kept singly
or with other large tough fish.
A coastal area brackish setup. A species tank.
Not a lot is known of their breeding and it probably can only be accomplished
in Brackish water. During courtship the pair will swim around each other
just above the bottom of the tank. Pale clear eggs are laid tightly
packed on rock surfaces. The male will protect the brood and uses his
body to cover the eggs. The eggs hatch in about a week and the male
will transfer the tadpole like fry to shallow pits and continue to guard
them. The fry can be hard to raise and feeding them can be difficult,
you should try a variety of small food including Brine shrimp nauplii
and observe which type they are eating. The mortality rate on the spawn
is usually high.
