The most common way for goldfish diseases to spread from tank to tank is through the use of the same equipment in 2 or more aquariums. The only surefire method of prevent cross contamination is to have a separate set of equipment for each tank. However this can be expensive and impractical, so it is important to sterilise equipment properly.

November 18th, 2008Hollow Ornaments
November 10th, 2008Hollow pond or aquarium ornaments come in all shapes and sizes, from sunken ships, to model houses, chinese temples, slightly open treasure chests, divers helmets, artificial wood, rocky caves, fake skulls, sea shells, or purely decorative. Unfortunately they are a bad idea.

The Fantail Goldfish
October 27th, 2008The fantail goldfish is a fancy goldfish, but it has more in common with non-fancy varieties. It can survive and compete successfully alongside common, comet and shubunkin goldfish in ponds and aquariums. It is also easy to breed, and an ideal fancy goldfish for beginners.
Aquarium Snails
October 19th, 2008Aquatic snails come in all shapes, sizes and colours. Their individual attractiveness is a matter of taste, but they certainly give an aquarium a more natural look, and perform some very useful functions to boot. Unfortunately, there are also some pitfalls that need to be avoided when keeping snails in a goldfish tank.

Goldfish Digestive System
October 6th, 2008Goldfish use a simple but efficient and interesting method of absorbing nutrients from their food. They have no glands, valves, or two sizes of intestine. Most unusual of all - even among fish - they have no stomach. Most surprising of all, they have a set of teeth to get the digestion ball rolling.

September 28th, 2008A Closer Look at Black Spot Disease - Part 2 (Parasites)
September 21st, 2008There are two very different fish diseases that get called ‘black spot disease.’ One is caused by healing after injury (most commonly ammonia burn), and the other is caused by a parasite that infects the intestine of birds. This second type of black spot disease is rare in fish tanks, but more common in ponds.
