A lot more colourful and interesting than the humble goldfish, Betta Splendens originate from the paddy fields of Thailand.
Progressively bred by aquarist's over the years these fish are now ocasionally available in a stunning variety of colour and form.
Although they can survive in a relatively small amount of water, Betta's should always be given a good sized tank with gentle aeration and a freedom from sharp objects (Betta's are weak swimmers and dislike strong currents, and they can easily damage deilcate fins on sharp rock or gravel).
Betta's do well at 26 degrees centigrade in mature water conditioned with Ocean Nutrition Atisons Betta Spa. Like all tropical fish, Betta's benefit from a large routine water change.
Betta's are generally hardy fish if kept in the correct conditions. They make amiable pets and have even been known to recognize and respond only to the person feeding them.
They should be fed sparingly on a varied diet with ocasional live food as a treat. Brine shrimp and frozen bloodworms along with proprietory Betta food makes a good choice.
Male Betta's should be housed singly since they will fight with others of the same species (hence the name!). They will also worry other females. They can be kept with other peaceful fish such as corydorus catfish and Plecs, but caution is the watchword.
If incorporating other tankmates, always err on the side of understocking rather than having too many fish. Using the surface area of your tank in centimetres (i.e. the length x width) a useful formula is LxW/40= total cms of fish length in your tank. E.g if your tank is 100x100cm= 10000/40 = 250 total cms of fish length. This is not an exact science and much will depend on your water quality and filtration methods. Aim to do at least a partial water change ever week, even with good filtration.
Have fun with your Betta, but always consider the welfare of your fish.About the Author:
