Deciding to bring new fish to a home aquarium, fancy colours, lively movements, and dazzling patterns are the things that can easily distract and get your attention in the first place. But the proper fish means more than these aspects.

First of all, it is very crucial to have a thorough knowledge of healthy ones so that you can choose them rightly, especially when you are looking for freshwater aquarium fish for sale.

Check the Tank Environment

Before focusing on individual fish, it is better first to find out the condition of the tank they are living in. The environment being healthy indicates the fish will be healthy as well. Besides, a good tropical fish store prioritises proper tank care, as poor water quality can lead to illness.

Behaviour of the Fish: Check for Activity and Responsiveness

The behaviour of the fish is one of the most reliable signs of health. Usually, healthy fish swim without interruption. When there is movement near the glass, they attract themselves, and generally, they are in interaction with their environment.

Fish that are hiding most of the time, lying at the bottom, floating near the surface, or even being unresponsive should be off your choice. Only those fish which show constant vigour and natural curiosity should be selected from among the freshwater aquarium fish for sale.
