Mike Ophir Long ignored as the maintenance crew of the community freshwater aquarium, the group of fishes commonly referred to as “Loaches” have clearly enjoyed increased popularity in the aquarium trade in recent decades. An increase in demand has resulted in an appreciation of the diversity of this loosely group assembly of species and yet, it […]

Stefan van der Voort reports on some new discoveries… Two studies published recently in the journal Zootaxa have revealed five new species of Badis. These works significantly increased the species richness of the genus in West Bengal, India, and hopefully pave the way for further exploration of that and surrounding areas.

Thomas Frank introduces three recent additions to the aquarium hobby… For loach-lovers 2008 was certainly not the worst year. It started in the middle of the year, when small loaches arrived in Aachen under the name Misgurnus anguillicaudatus but which could easily be identified as members of the genus Cobitis.

In the first of a series of articles in support of BIAZA’s ‘Big Fish Campaign’ we explain why, in […]

It is often said that a tiger never loses its stripes, but what about its name? Matt Ford investigates… Cases in which a fish long thought to be one species turns out to represent something else are not especially unusual within the aquarium hobby. Notable examples include that of the ‘arulius barb’, for many years […]

A number of aquarium favourites have new scientific names following a recent study. Here’s a handy guide to the changes. Barb fans beware; an extensive review of South Asian Puntius spp. published in the latest volume of ‘Ichthyological Exploration of Freshwaters’ has resulted in a large portion of the genus being split up and many species placed in […]
