Aquarium Keeping Ideas

A major Real Estate company, Redfin, included me in their blog article ’14 In-Home Aquarium Ideas….’.  I am honored that they chose me as their expert on planted tanks.  Article promotes home aquaria and provides an overview of aquarium keeping with web links to other experts.

Potted Plants for Fish Tanks

Fish Breeding without Pumps and Filters

My new article ‘Potted Plants for Fish Breeding Tanks’ describes maximizing plant growth so that I can keep 10 fish breeding tanks without any filters. Keeping plants “mobile” (i.e., in pots) makes it doable. I measured no NH3, no NO2- and almost no nitrates in the 10 tanks over the course of several months.

Guppy Genetics

Revision of 2020 Guppy Genetics Article

I revised my 2020 article ‘Breeding Guppies: Genetic Pitfalls and Successes‘.  Revision containsapril-18_2018-1 same basic material, but I simplified article.  I spent more time discussing popular mutations that can perplex beginners.  And I down-sized a complicated discussion on the genetics of swordtail guppies.   It was not that relevant in successfully outcrossing my beautiful delta-tail females (Photo) with male swordtail guppies.   These outcrosses were wildly successful and I had no trouble breeding out the swordtail trait.

Guppy Longevity

Older Female
Older Male

My 2022 revised article Guppy Longevity (10 pages) answers the question of why fancy guppies don’t live that long.   It puts much of the blame for guppy fragility onto the common practice of using only young fish as breeders.  The long-term result is detrimental genetic changes. Since I started using only older fish as breeders, I’ve increased the longevity of my fish from ~6 months to over 12 months.  Photo shows a 15-month old male and female.   Still room for improvement, but this is progress.  

Brine Shrimp for Aquarium Fish

Harvested 3-day-old Shrimp

Hatching and Growing Brine Shrimp (Artemia) is–I believe–the ultimate brine shrimp article for aquarium hobbyists. Starts with hatching eggs in a soup bowl without aeration. Moves onto ‘hatching dishes’ that automatically separate nauplii from shells, making harvesting fresh nauplii incredibly easy. More new subjects include cold storage of harvested nauplii, feeding fish decapsulated eggs, why lower salinity works best, and growing shrimp out for 3 days. Author discusses the many factors (osmoregulation, iron nutrition, sensitivity to heavy metals, etc) that affect hatching success.
