Killifish, Goodeid livebearers (aka splitfins), aquarium plants and articles.
Below are PDF files of the article's two parts. The first part deals with the nature of freshwater systems and the risks that freshwater fish (and other freshwater animals) face nowadays. The second part deals with what aquarium hobbyists can do about it.
English version of an article I have written for Botia journal, published (in Finnish) there in March 2023. (Cover/Background image credited as in Figure 8 [see figure sources at the end of article].)
A great beginner killie. Peaceful and non-aggressive. They gather in a loose shoal near the surface or in mid-level. Extremely hardy and adaptable to different water parameters. Are not "jumpers". Not picky eaters - will gladly take any dry, frozen or live food. A non-annual killie that can live quite long, and is very easy to breed. Endangered in their native Madagascar, so captive breeding is encouraged.
An endangered livebearer from Mexico, with a nice combination of orange and blue coloration.
Endangered livebearer from Mexico. Hardy and adaptable species.
I describe my experience with some killifish species, and list them in order of increasing ease of care and breeding.

This small blue-green gem (or pearl) of a fish from Paraguay and Argentina should be kept in its own species tank. A small group of several males and females can be kept together for breeding. Prefers live food.

Annual killie from Brazil. A relatively large-sized annual (up to 11 cm; though remains smaller in the aquarium). A very easy and durable species, perfect as a beginner killie.
