The most common warm water fish

Warm -water fish are a good choice as pets, but they require more care than cold-water fish . Are you thinking of setting up a fish tank at home? We will tell you about the most common warm water fish and their care.

Basic care of warm water fish

First of all, these fish will need a specific tank that is capable of withstanding the right temperature for them to live.

You will also need a thermostat so that the water is kept at a constant temperature, between 24 and 28ºC .

Also, when selecting which fish you want to have, you should consider that  there are some species that do not get along very well with others. Ideally, you should consult a specialist before selecting these animals at random.

What kind of warm water fish are there?
