I am displaying bowls with Neocaridina shrimp for the Raleigh Aquarium Society’s annual workshop. I set up two 1-gal bowls with shrimp taken from my guppy breeding tanks. I used a 7.5 watt reptile heating pad to keep bowl water temp at a nice warm 74F for good plant growth. (Winter house temp is 65F.) Shrimp article on my aquarium page here describes setup for bowls. Lighting for red shrimp’s bowl is 13 watt CFL. For blue shrimp’s bowl, I have a 3 watt LED desk lamp plus window light.
For first 1-2 weeks I have had to change 80% of water almost every day to remove ammonia and nitrites. (The 2 cups of potting soil was probably too fertile; I probably should have diluted it with sand.) Most important for shrimp health, I only use aged aquarium water from the guppy tanks for water changes. [The DOC (dissolved organic carbon) in aged aquarium water protects the shrimp.] I don’t need or use the drip method, but I when I pour water into the bowls, I always use a small cup to block the water’s force. That way, the incoming water does not disturb the soil layer.
The RAS workshop [March 24-26, 2023, Raleigh, NC (USA)] will have native fish collecting, talks by fish, plant and shrimp experts, an auction, shrimp judging contest, banquet, etc. I have been going for decades. Later in the year, I’ll revise my shrimp article based on what I learn at the workshop from a shrimp expert (Robert Lupton) and from setting up these new 2023 bowls!
This 2022 revision of my article Small Scale Guppy Breeding describes how I breed fancy guppies in just nine tanks. Articles covers the basics, but it contains new, vital information on guppy reproduction. Learn why I keep “chase” females with my juvenile males, why one female accepted and quickly mated with a new male but her full-sister rejected him… Learn the pros and cons of separating the sexes, how I breed for fitness… Overall, the article celebrates the guppy’s genetic trait of color polymorphism. Unlike breeding methods that emphasize strain uniformity, I work with the guppy’s natural tendency to produce different color patterns (Photo). This not only makes guppy breeding more fun but avoids inbreeding problems and genetic weaknesses.
Article on setting up small planted tanks for pet shrimp.
Small Planted Tanks for Pet Shrimp (9 pages) 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. Bowls shown at 1 month in photo were off to a good start and continued to do well. For hobbyists who want to try something a little different, I describe setting up small tanks with the Dry Start Method (DSM). With DSM, 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.
