Small-Scale Guppy Breeding

Small-Scale Guppy Breeding’ is a general article on how I keep and breed fancy Guppies in ~8 planted tanks.  You won’t see anything about fish rooms, drilled tanks, automatic water changers, etc.  It covers paternity issues and explains how I deal with the modern Guppy’s fragility and disease susceptibility.

Flukes and Sick Guppies

Flukes and Sick Guppies (8 pages) tackles the problem of why guppies die for “no good reason.” It starts with the author’s own discovery of Monogenean flukes as being a major and long-standing problem for the guppy (Poecilia reticulata). The disease management strategies she now uses are based on recent scientific papers and the ecology of flukes and guppies

Parasite Surveys

Which parasites are most prevalent in tropical aquarium fish?  My article Parasite Surveys of Aquarium Fish, a compilation of 11 different investigations from around the world, answers that question. Freshwater fish (goldfish, guppies, tetras, etc) were sampled from Sri Lankan fish farms, Swedish pet shops, etc.  Most surveys reported Monogeneans (i.e., flukes) as the most common parasite of aquarium fish–whether healthy or diseased.  For example, 37% of 223 freshly caught wild fish from the Amazon carried Monogeneans, ranging from a 92% prevalence in Angelfish to only 7.4% in Cardinal Tetras.  The ICH parasite was in second place (21% prevalence in the 223 fish), but other studies reported a much lower prevalence of the ICH parasite. Overall, Monogeneans dominated.

Treating Fish for Nematodes

Over the years, I have had to deal with nasty Camallanus worms three times in newly purchased fish. My article ‘Treating Fish for Camallanus and Other Nematodes’ contains step-by-step instructions for preparing a Fenbendazole-containing fishfood that successfully rid my tanks and fish of these intestinal parasites. I have included information on other treatment options, the related nematode Capillaria, plus the worldwide presence of Camallanus in both native fish and the aquarium trade.

Raising Brine Shrimp for Aquarium Fish

Hatching and Growing Brine Shrimp describes a new, and I believe, better method for providing aquarium fish with the world’s tastiest and most nutritious food. After hatching the eggs, I grow out the shrimp for 3-4 days in bottles seasoned with bacteria and micro-algae–food for the shrimp. Resulting juvenile shrimp are bigger and more nutritious than starved nauplii. My method saves expensive eggs and reuses the saltwater.

Mycobacteriosis in Aquarium Fish

Mycobacteriosis in Aquarium Fish, a 15 page article, provides vital information that fish keepers can use to prevent—or deal with—“Fish TB.” Scientific surveys show that almost half of fish deaths due to unknown causes are due to mycobacteriosis. Article is based on the author’s experience fleshed out with the latest scientific research. Every fish keeper, whether professional fish breeder or beginning aquarium hobbyist, should read this.

Small Shrimp Tanks

Small Planted Tanks for Pet Shrimp (PDF, 700 KB) was written for people wanting to keep planted tanks.  I show how to set up 1-gal bowls with small shrimp, which is an easy, inexpensive way to get started.  For hobbyists who want to try something a little different, I describe setting up small tanks with the Dry Start Method (DSM).  Here, aquarium plants are grown emergent (in air) for the first 2-3 months before adding the water and the shrimp to the tank. Both methods involve using ordinary soil as a planting medium and keeping Red Cherry Shrimp, which are hardy, colorful, and cute.
