Tropical fishkeeping

What is the best tropical fish for a beginner?

Guppies and tetras are the ideal fish for first-time owners. They are eye-catching yet hardy, with low space requirement and high tolerances, and are happy to co-exist with one another and most other small fish.

Can different species of tropical fish be kept in the same tank?

The short answer is yes, but there are lot of variables to consider. Different species have different size requirements and general behaviours, which need to be considered before you purchase them or pair them in the same tank. Guppies, rasboras and tetras are famously able to get along, but larger carnivorous species like cichlids will attack and even eat smaller fish. Different species may also have different pH and temperature requirements. Please ensure you research a species before you purchase. Alternatively, get in touch with us via a contact form and we will be happy to advise you.

How many fish should I start with?

This is up to your confidence and the space you have available. A general rule of thumb with smaller fish is 1 fish per gallon of water, and 1 fish per 3 gallons of water for later fish. Keep in mind, however, that there is a difference between a fish thriving and surviving – You could keep 3 tetras or 1 catfish in a small 3-gallon tank, but these will not be happy or well-stimulated fish.

Do I need plants as well?

Fish in smaller aquariums can do without them, but aquatic plants are an easy way to improve water quality. Most species of aquatic plant will reduce the spread of harmful tank bacteria by absorbing and recycling nutrients produced by fish waste. They also provide fish with a place to hide, which has been proven to reduce stress and improve their quality of life.
