Fish farming

Breeding fish in a home aquarium isn’t as easy as simply sticking a male and female of the same species together and hoping for the best—it requires careful preparation and monitoring. After you’ve researched the specific mating habits and preferred living conditions of the species you’re trying to propagate, your first step will be to select a healthy parent candidate of each sex. You’ll then need to carefully engineer key tank conditions like water temperature, pH level, lighting, and surrounding flora to make them more favorable for mating. These environmental changes help “set the mood” for the parent fish and ensure a successful coupling.


Aquaculture makes use of local photosynthetic production (extensive) or fish that are fed with external food supply (intensive).

Extensive aquaculture

Neon Tetra

Neon Tetras are a small, easy to care for species. This popular aquarium species is often one of the first fish a beginner aquarist will buy.
They reach around 2.2cm in length, and like to be kept in groups. They are a great choice for small community aquariums due to their peaceful temperament.

Neon Tetras come in bright colors, and have an iridescent blue horizontal strip across their body (so they are visible in dark waters).


This colorful and lively fish is able to adapt to a variety of water conditions which is one of the reasons they are so popular. They are also very easy to care for. You should keep guppies in sets of threes, and a good guide for the tank size, is 1 gallon of water per guppy.
Males are much more colorful and vibrant than females, so if you’re not looking to breed, you may want to just keep males.
The ideal water temperature for guppies is 50OF – 84 OF (10-29OC), but the most important factor is that the temperature is kept consistent.


Oscars are thought to be one of the most intelligent aquarium fish available, and are one of the few species that can be trained to dot
Oscars however are not a community fish, they should be kept in a species only tank, and they can grow very large, very quickly.
They require a lot more maintenance than other fish, due to their carnivorous nature and the amount of waste they create.
On the positive side, they are one of the few species you can hand feed; they will often eat food from between your fingers. Oscars thrive when kept in pairs, or group of 5+, and should be housed together from a young age.


This small, peaceful species grow to around 3-4 inches, and adapt well to a variety of water conditions.
The ideal tank conditions are: a minimum tank size of 20 gallons, and warm water with a pH between 7.0-7.8.
Mollies are omnivorous, and will require a diet of both plant and animal food.
Interestingly, they are livebearers, meaning they give birth to their young live, rather than lay eggs. Mollies are very easy to care for, but they also breed very easily, so if you’re a beginner you might want to keep just a single sex.


Platies come in almost every color imaginable and they are very easy to care for – just two of the reasons why they are so popular.They are a great community fish, they’re very peaceful and get along well with guppies and mollies.
Although small, platies are very active and love being in groups. A 10 gallon tank is large enough for 5 fish.
Whilst they are omnivorous, they do require much more herbivorous food, than meats. Ideally, they need a good mix of plant based food and proteins.


Freshwater fish come in a huge variety of shapes, colors and sizes. The most popular fish are usually bright, colorful and easy to carefor.If you’re new to fishkeeping, I recommend starting slowing and adding just a few fish at any one time. This will give you chance to get to know and understand how to care for each species of fish before you add another.
Make sure you always research the species you want to buy to ensure you can give them the time and care that they require. This article should only serve as an example of the popular types of freshwater fish, rather than a guide on how to care for each one. For guides visit our breed care guides here.
