One of the most popular and commonly seen Synos in the hobby, S. eupterus is usually offered for sale as a small (1-3") juvenile with no information regarding its potential size. These young fish are often sold as Synodontis "Network" due to their attractive reticulated patterning. This patterning breaks up as the fish mature and adult specimens have a simple spotted colouration. The characteristic 'feathered' dorsal also develops with age, with the first few rays develo...

This is one of the most common Synos seen in dealers' tanks and is often incorrectly labelled "Upside-down catfish". The true upside-down catfish is S. nigriventris and S. nigrita inverts far less frequently than that species although it does often rest in this position. Moreover, S. nigrita grows far larger than S. nigriventris and it is a common sight to see several adult specimens in shops that have been returned by unsuspecting owners. S. nigrita is often confused with the...

Similar in lifestyle to Julidochromis species, Telmatochromis vittatus is ideal for the smaller Tanganyikan community and is also a good choice for the beginner. It can be distinguished from the similar T. brichardi and T. bifrenatus primarily by its larger size, smaller eyes and more rounded nose. Like other Lamprologines, Telmatochromis have fang-like, caniform teeth, which they use for scraping microrganisms from rock surfaces. On adult specimens these are clearly visible....

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 ...

A rather elusive species in the hobby, this beautiful cichlid is sometimes referred to as the "Chisel-toothed" cichlid. Despite being described in 1902 it was not until the mid-1990s that it appeared in the aquarium trade, wild specimens being collected by American aquarists Ross Socolof, Harry Specht, and Rusty Wessel in 1994....

This species is also sold as the 'redline' rasbora which is something of a misnomer as in reality the colour of the lateral stripe that gives rise to the name can vary from deep orange to golden depending upon the collection locality of the fish as well as diet, condition, and even mood. Some specimens also have a second, darkish stripe beneath the other which seems to vary in length and intensity depending on a similar array of factors. Older fish tend to possess a greater degree of black edging to the scales, especially in the ventral portion of the body.

T. heteromorpha was first exported for aquaria in the early 1900s and has gone on to become one of the most familiar, enduring species in the hobby. It has suffered as a result of its popularity to a certain extent with the mass-produced fish we see today lacking much of the colour seen in wild specimens and even exhibiting morphological deformities in some cases. Several selectively-bred ornamental strains have also...

This species is clearly not an aquarium fish, and thankfully is not imported with any great regularity. Young specimens are occasionally seen for sale however and no matter how cute they look, don't be tempted to buy one. The gigantic adult size is not the only problem with W. attu, as the mouth is filled with needle sharp, backward-pointing teeth. The fish will bite aggressively when being fed, especially when handled and larger individuals could easily sever a hand or worse. It is a genu...

Y. eos isn't as commonly-traded as it once was but is still available occasionally. It's difficult to confuse with any other member of the genus due to its colour pattern consisting of yellow to reddish brown base body colour (can appear greyish in some specimens, especially post-import or when introduced to a new aquarium) with a metallic green/blue golden sheen and large darkish marking on either side of the caudal peduncle. The fins can be yellowish to reddish, and the dorsal and c...
