Choosing your fish for a balanced look

There are many different fish types, shapes and sizes. Due to their natural habitats and their physical design, different breeds of fish have different preferences of where they like to hang out in the aquarium. Some like to be at the top, others prefer to reside on the base of the aquarium. Try and vary the fish you keep for a balanced community look.

Below are a few ideas of fish species that you might like to keep in your aquarium, and where they generally like to spend their time. These fish cannot necessarily be kept together - and growing sizes would need to be taken into consideration (see – How many fish?) - but these are few ideas to get you inspired.

Siamese Fighter (Betta)

Betta, otherwise known as Siamese Fighters, are very attractive fish that come in many colors - commonly blue or red. The males have impressive, long fins but are territorial and should be kept alone, or only with females. Never keep two males in the same tank and avoid keeping with fish that like to nip fins. Adult size (without fins) up to 3".


Guppies are colorful, fun, active little fish that will liven up a community aquarium. The males are more colourful with bright fins and tails, available in a rainbow of colors - sometimes patterned. These fish are livebearers, meaning the females give birth to live young rather than laying eggs. Keep males and females together and you'll soon have new additions to your aquatic family. Guppies come in various sizes but can grow up to 2.5"
