Dwarf Parrot Wrasse (Cirrhilabrus rubriventralis) Family: Labridae
 
If I was asked to name one group of fish which featured a wealth of attributes such as beautiful coloration, tireless activity from dawn to dusk, ease of feeding, a generally peaceful nature, compatibility with invertebrates and disease resistance, I would lay odds that the questioner would not be expecting a realistic reply.

Harlequin Tusk Fish (Choerodon fasciatus) The harlequin tusk (Choerodon fasciatus) belongs to the family of wrasses. It has orange mottled bands. Each band is etched by delicate blue-violet ribbons. Anteriorly, between the orange bands is silvery-white, turning to dark grey-black posteriorly. With big protruding tiger-like fangs, the tusk looks very menacing indeed, capable of doing harm to other tank mates.

Clown Tang | Acanthurus lineatusThe Clown Tang (Acanthurus lineatus) is one of the most striking members of the Tangs / Surgeons family (Acanthuridae), being one of the most aggressive and can be challenging to keep and care for. It is also known in the trade as the Lined Surgeon and Pyjama Tang.

Sooner or later as a reef tank hobbyist you're going to want one of these beauties. They are reef safe and live harmoniously with corals and invertebrates.

Clown Trigger Fish

One type of marine aquarium never fails to create a stir, the fish-only tank containing BIG fish! The sight of large slices of brightly coloured piscine flesh cruising around an equally spacious aquarium is enough to make anyone's heart beat a little quicker. Such displays are normally the province of the public aquarium, but within the confines of a domestic setting the whole thing can be replicated on a somewhat smaller scale with equally stunning results.

Blood Shrimps (Lysmata debelius) Most of my regular readers will already be aware that, on the whole, I do not condone small marine tanks; that is, tanks with a nett volume of less than 20 gallons (91 litres). They are usually very unstable as far as water parameters are concerned and subsequently exert considerable stress on fish and/or invertebrates. They are also extremely restricting for livestock and consequently prone to overstocking, especially where fish are involved.

Having said that, there is a way that the marine enthusiast can set-up a 'micro' marine aquarium housing only shrimps! Over recent years, I have been experimenting with 3-5 gallon marine aquaria containing various species of tropical and temperate shrimp and crabs. I am pleased to report that all tanks were successful and no livestock was lost.

Cyphotilapia frontosa A pair of Cyphotilapia frontosa from the authors aquarium.

One of the most beautiful and distinctive Cichlids of Lake Tanganyika has to be C. frontosa. There are two colour morphs of this species, a Berundi morph, which has six vertical bars and a Tanzanian morph, which has seven or even eight bars when they are young, although in my experience I have only ever encountered the Berundi morph. The males develop a huge lump of fat on the top of its head making this a very distinctive occupant to any aquarium.

Distribution and Form  These ancient animals occupy all the oceans and seas of the world and species are to be found throughout the very coldest to the very warmest regions, such is their ability to diversify and adapt, albeit over aeons of time. Anemones are very closely related to stony corals, but whereas stony corals are made up of polyp colonies, anemones can be seen as one large polyp. Accordingly, the structure of an anemone is extremely simple and has changed remarkably little over millions of years. They are basically a ' [ ... ]


ConservationFishing With Cyanide - Coral Reef Genocide
The Coral Reef Alliance

Cyanide Fishing Destroys Coral Reefs Cyanide, one of the most toxic poisons known, is being used to catch live fish in the South Pacific and Southeast Asia. Fishermen stun fish by squirting cyanide into the reef areas where these fish seek refuge. They then rip apart the reefs with crowbars to capture disoriented fish in the coral where they hide. In addition, cyanide kills coral polyps and the symbiotic algae and other small organisms necessary for healthy reefs.


BettasRaising Betta picta
Jan Hvizdak

Betta picta get their Latin name from their distinct colouration and markings, the word “picta” depicting painted. Their markings comprise of three horizontal bars which are not solid but are made of from a series of dark dots. Their main body colouration is a greyish/brown with the males displaying coloured margins on their fins. They reach an adult size of just over two inches and in the wild they inhabit fast flowing waters which have high oxygen levels. They are to be found Sumatra, Java and Indonesia with the earliest imports reaching our aquariums in the 1930’s.
