Puffer fish are so called as they have the ability to inflate their elastic stomachs with water or air. This is usually a response to some kind of threat, although in the aquarium many specimens appear to inflate themselves for no apparent reason. The fish becomes 2 or 3 times its normal size, big enough to scare away many potential predators, or difficult to swallow. Puffers also have several other interesting adaptations. They are one of the few fish that can actually blink or close their ...

Puffer fish are so called as they have the ability to inflate their elastic stomachs with water or air. This is usually a response to some kind of threat, although in the aquarium many specimens appear to inflate themselves for no apparent reason. The fish becomes 2 or 3 times it's normal size, which makes the fish both big enough to scare away many potential predators, and difficult to swallow. Many parts of the body of puffers contain the deadly neurotoxin tetrodoxin. This is the same ...

An attractive but not often seen species in the hobby. This is quite odd considering how common it is in many of its native habitats, where it is known as sardina. It has very strong pectoral muscles, and uses these to jump from the water to catch flying insects or to escape potential predators. It can make leaps of several metres in length....

T. macrostoma is an ambush predator in nature, lurking behind rocks and in crevices as it stalks its prey. It is rarely seen in the hobby and is usually quite expensive. Juveniles are easily confused with the similar T. nigriventer, but are easily distinguished when adult, as nigriventer does not develop the dark belly of macrostoma. Interestingly, this species exhibits reverse countershading, as also seen in the common Upside-down catfish, Synodontis nigriventris. This means that unlike the...

Wallago are fearsome predatory catfish that are fairly widespread in southeast Asia. There are currently five recognised species, W. attu, W. leerii, W. hexanema, W. maculatus and W. micropogon. The latter was described to science in 2004 by renowned catfish expert Heok Hee Ng and was previously considered to be a geographic variant of W. leerii. All members of the genus possess an enormous mouth full of backward pointing teeth, which are used to rip chunks from their prey. Smaller fish or amphi...

Puffer fish are so called as they have the ability to inflate their elastic stomachs with water or air. This is usually a response to some kind of threat though in the aquarium many specimens appear to inflate themselves for no apparent reason. The fish becomes 2 or 3 times its normal size, big enough to scare away many potential predators, or become difficult to swallow. Puffers are also one of the few fish that can actually blink or close their eyes. Many parts of the body of puffers contai...
