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.
Revision of 2020 Guppy Genetics Article
I revised my 2020 article ‘Guppy Breeding: Genetic Pitfalls and Successes‘. Revision contains 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.
