Freshwater fish are a popular choice of pet and the preferred choice of marine animal for those getting started with aquariums. However, taking care of freshwater fish requires plenty of focus if you want your animals to thrive. If you\u2019re interested in purchasing an aquarium and want to stock it with freshwater species, you\u2019ll need to observe a few basic approaches to maintenance to ensure good results.<\/p>\n
Before you start thinking about water maintenance and dietary requirements, you need to ensure you are picking a suitable aquarium for freshwater fish<\/a>. There\u2019s a huge range of options when it comes to fish tank sizes, with plenty of models suitable for freshwater species. No aquarium is too small for housing freshwater fish, although a more modest tank will limit the amount of fish you can keep at any one time.<\/p>\n Different freshwater<\/a> species have their own requirements, with many breeds only thriving when kept in larger groups. A larger group will of course require more space. If you are limited to a small aquarium, betta fish<\/a> make a good option. Betta species are generally quite aggressive, especially males, so tend to prefer solitary living conditions. They\u2019re also quite content with less swimming space, while their colourful bodies and elaborate fins more than make up for a limited aquarium population.<\/p>\n You\u2019ll need to be careful when maintaining water conditions if you want your freshwater<\/a> fish to thrive. Before you think about adding pure tap water to a fish tank, you\u2019ll need to first condition it. Tap water contains chlorine, which will need to removed before you can introduce freshwater fish to it. You should also aim to add biological supplements to your aquarium water before introducing fish to it.<\/p>\nMaintaining Optimal Water Conditions<\/h2>\n
