Video on Small Bowl Setup

Small bowls are a simple, inexpensive way of keeping aquarium plants and moving on to bigger things. A YouTube video (‘The Simplest Planted Aquarium With Diana Walstad’) shows the setup of 1-gal and 5-gal planted bowls. Lisa and John Hudson of KGTropicals (keepfishkeeping.com) made this happen. Video is a fantastic learning piece for those of you rightly intimidated by setting up aquascaped tanks, using soil in aquariums, or maintaining high-tech tanks. Photo shows me and Lisa with our bowls. She’s got the bigger one, but I’ve got three little ones. Not surprisingly, all bowls are doing great since setup!

Indexing Scientific Papers

Without my ‘Aquatic Ecology Subject Index’ (175 pages, available here), I never could have written Ecology of the Planted Aquarium.  From the 1990s onward, I subject-indexed every scientific paper I read.  Eventually, the index provided a framework for my book.  I enjoy reading scientific papers.  Many contain  interesting experiments and inspiring ideas.  Admittedly, the scientific jargon, conflicting nomenclature, and statistics can be daunting.  But these barriers can be breached by further investigation and being organized.  To be a scientist, you do not have to have a Ph.D., but you do need a love of science.

2023 Shrimp Bowls

One of my Red Neocaridina Shrimp (RCS)

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.

Bowl for Blue Neocaridina Shrimp

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!

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.
