How to Choose Between Freshwater, Tropical, and Marine Fish

So, you want to add some color to your life and welcome some fish into your home? They can be a great addition to the family for so many reasons! If you’re feeling a little lost about which ones to get, then here’s how to choose between freshwater, tropical, and marine fish.

The water

Freshwater fish need just that: freshwater! It’s best to buy a conditioning solution that can be added to the water to remove any unwanted chemicals that could be harmful to our fish. Both freshwater fish and tropical fish need their temperatures controlled, but tropical fish often have a more specific temperature range depending on the species. Marine fish? They need special water that often has to be bought from a specialist. This is usually collected from the sea and balanced so that it’s ready to use.

The food

There are plenty of types of fish flakes that give your freshwater and tropical fish all they need. However, some people prefer to feed their fish frozen or dried food, such as shrimp, plankton, or bloodworms. These are great options for carnivorous species of fish, so be sure to research your fish to make sure they have the right diet. Marine fish are different as they live in saltwater. Most breeds of marine fish thrive on different types of microalgae or macroalgae.

The setup

Freshwater fish need a filter to keep the water fresh and may require a heater depending on your climate. Tropical fish need a water filter to keep the water clean and to help add oxygen to the water as well as a heater and thermometer to make sure their tank is the right temperature at all times. Once again, marine fish also need a heater, but that’s not all. These fish also need a secondary filter known as a sump that sits underneath the main tank and filters the water, as well as powerheads to keep the water moving.

The costs

One of the main aspects to consider is the cost of your new fish. Freshwater fish are the cheapest option on the market and don’t typically cost too much to maintain. Tropical fish tend to be a little more expensive, depending on the species that you want. They can also cost a bit more in the long run. Marine fish are the most costly option. Individual fish could set you back hundreds of dollars, while the water can be an expensive addition. To top it off, marine fish also need live rocks and plants that are filled with bacteria and microorganisms that help keep your tank balanced.

There are so many things to think about when choosing between freshwater, tropical, and marine fish. It’s all about considering the time, money, and effort that you are willing to put into your new additions as well as the type of fish you want in your home. Thankfully, there are plenty of specialist stores that are filled with knowledgeable people to make sure you get everything you need for your new additions.
