Something for the true oddball enthusiast, this bizarre looking goby has been imported at least once over the last few years. It's a mud-burrowing species that digs networks of sloping tunnels in the substrate in nature. Apparently each series of burrows has several openings, one of which has a mound outside. According to Itani and Uchino (2003), this mound suggests that the fish "actively process sediment". Even more odd is its appearance (see picture). It has greatly reduced eye...

This is one of the so-called Tanganyikan Goby Cichlids. They occur only in the upper few feet of water around rocky shores, also known as the surge zone, where they scrape algae from the rocks with their specialised teeth. This habitat is typified by breaking waves and strong currents. They have a few adaptations allowing them to inhabit such an environment. The swim bladder is rendered useless to reduce their buoyancy. They also have a longand a laterally compressed body shape to allow them to ...

One of the most ubiquitous species in the hobby and several ornamental strains are available including 'long-finned', 'golden', 'albino', and 'super red', for which care is identical to that of the 'standard' fish. Unfortunately the degree of inbreeding amongst farm-bred stock has resulted in a situation whereby many of the fish available today are genetically weak and prone to disease or develop physical deformities.

This species only became available in the aquarium hobby during the early 21st century but has already achieved a measure of popularity since it's attractive, easy to maintain and usually quite cheaply-priced. You may see it on sale under various trade names including 'Vietnamese minnow', 'cardinal minnow', 'royal white cloud', 'dwarf cardinal' and others. We've obtained images of what is said to be a naturally-occurring form with extremely elong...

This fish was first collected in 2009 and limited numbers have been available in the aquarium trade. Though additional exports may be unlikely it's proven easy to breed in captivity and there's a fair chance it will become established in the hobby. It's sold under several names including T. sp. 'lemon' or 'yellow white cloud', and has also been misidentified as the congener T. thacbaensis, a valid species occurring much further north in Vietnam.

This beautiful little fish is not actually a goby, it's a member of the Eleotridae family, commonly known as sleepers or gudgeon. Members of this family lack the fused pectoral fins of true gobies. This species is one of the smallest and most attractive in the family, and makes an ideal resident of the planted community tank....

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 ...

This species has been a popular aquarium fish for a considerable period and virtually all fish traded are now raised commercially for the purpose. It is easily identified by the characteristic bright red or orange underside of the head, which is more pronounced in adults. Following Miller and Taylor (1984), the genus Thorichthys is identified...

The Largescale Archerfish is one of a fascinating group of fish that have evolved this very distinctive feeding pattern. The family contains six species, of which toxotes jaculatrix is the most commonly available (sometimes sold incorrectly as t. jaculator). Toxotes chatareus is offered for sale in the UK although much less frequently. There are reports that juvenile archers can be kept in fresh water but it is recommended that a brackish setup is always used. Eaten as a food fish in many...

The Banded Archer fish is one of a fascinating group of fish that have evolved this very distinctive feeding pattern. The family contains six species, of which toxotes jaculatrix is the most commonly available (sometimes sold incorrectly as t. jaculator). Occasionally, the similarly marked toxotes chatareus is offered for sale in the UK although much less frequently. There are reports that juvenile archers can be kept in fresh water but it is recommended that a brackish setup is always used. ...

Very similar to its congener T. exilis, it can be distinguished by looking at the position of the eye which is set much further forward in exilis. Also, the humeral process (long spine extending from the back of the gill plate), is broader and shorter in this species than exilis. Neither are seen very often in the hobby....
