Tropical Fish Hobbyist December 2009 Issue

Gracing our shiny year-end cover this month is a group of Pacific sea nettles Chrysaora fuscescens featured in the “Jellies Invasion” exhibit at the National Aquarium in Baltimore. Found mostly off the West Coast of the United States, these cnidarians represent one of many species that have recently caught the attention of progressive marine aquarists. Our cover story, “Feeding Jellyfish: Problems and Solutions” (p. 90) tells of the trial-and-error search for the best way to feed captive jellyfish—the type of research typical to any vanguard investigation in the aquarium hobby.

Live Sand – what is it?

Live Sand – what is it?

Live Sand (“LS”) is essentially a combination of non-living substrate with a myriad of tiny beneficial life forms that grows on it. It is home to many microscopic biological bacteria. LS can form as a main base for biological filtration in a marine aquarium, while the living organisms in the sand bed can help consume the organic matters. LS can be collected live from the ocean, or can be cultured from a non-living oral sand to make it live. The quickest method in starting a marine aquarium is to use 100% LS which are commercially sold in bags. Using this method, there is no waiting period or delay in the biological cycling process for the beneficial bacterial to establish themselves... Read more»

Guppy – fish fact

Guppy – fish fact

One of the cheapest, most popular and yet beautiful fish that every aquarist is familiar with, is the Guppy (Poecilia reticulata), also known as the millionfish. Belonging to the Poecilidae family, Guppy is a small fish with the females growing to 4–6 centimetres long and the males 2½–3½ centimetres long. This fish is live-bearing and are often bred for their natural colour. Breeding Guppy is very easy. Courtship starts when males spread their fins and curve their body in front of the females. The male will swim up against the female to mate. Once the female is inseminated, a dark area near the anus, known as the gravid spot, will enlarge and darken. The gestation period of Guppy is between... Read more»

goodbye! PO4

goodbye! PO4

Singapore formulated phosphate (PO4) for marine aquarium is launched into the local market, and it is “goodbye! PO4“. goodbye! PO4 is a liquid phosphate remover which operates hand in hand with a protein skimmer or a mechanical filter. It works by binding active phosphate molecules, turning them into inert particulates which become unusable for further biological processes. That means it is unavailable as a nutrient for algae growth and will not affect corals’ well being. The particulate suspension is subsequently removed from the aquarium system by protein skimming and/or through the mechanical filter. Understanding Phosphate (PO4): Phosphorous is an essential element in all living... Read more»
