Keeping an aquarium at home is a demanding but rewarding hobby. You must first choose the right fish, tank size and installation to build a beautiful and balanced aquarium. Most importantly, you have to choose from what kind of fish to keep fresh water or navy. This can be an exciting but confusing decision for anyone who sets up an aquarium. To help you make the right choice, we list certain things you need to think about to choose the right aquarium fish for your home aquarium:1. Maintenance and difficulty levelFreshwater aquariums are beginner -friendly and easier to maintain. The fish are hardy and the water parameters are more forgiving. You only need basic cleaning, filter changes and regular feeding. On the other hand, marine aquariums require more attention. Salt water fish are sensitive to even small changes in temperature, pH or salinity. You need specialized equipment such as protein shimmer and marine salts. If you are new to fishing ping, start with fresh water species for experience. But if you are ready for a challenge and love the idea of colorful corals and exotic marine species, a salt water set can be worth the effort.2. Installation requirements and how much would it costFreshwater sets are generally more budget -friendly, while Marina Aquarium sets are more expensive. You can start with a simple tank, filter and lighting system. Most freshwater fish, plants and decorations are also affordable. However, marine thoughts are more expensive due to the need for high quality salt mixtures, test rates and advanced filtration systems. Even the fish itself often costs more. Maintaining salinity and coral health provides ongoing expenses. So if you are looking for a low -cost hobby, fresh water is the way to go. But if you are ready to invest in a fantastic underwater ecosystem, a marine tank offers unmatched beauty and diversity.3. Variation and color of fishNavy fish are known for its bright colors and exotic looks. Some fish species such as clownfish, tangs and angelfish add fascinating beauty to your aquarium. At the same time, freshwater fish are relatively less flashy. However, there is a wide range of fish with charming personalities to choose from. You can choose between beta, guppies, tetras or cichlids, each adds life and movement to your tank.4. Tank size and space restrictionFreshwater tanks are available in different sizes and can fit even in smaller spaces. You can start with a 10-20 gallon tank for beginners. However, marine fish usually needs more room to thrive, as they are territorial and require stable water chemistry. Most salt water sets start at 30 liters or more. In addition, coral reefs or live stones need plenty of room for proper growth. If you live in a small apartment or want something compact, a freshwater container is more practical. But if you have space and want a showpiece aquarium, a large marine installation is an impressive choice.5. Maintenance and Time SettingFreshwater tanks need less time for maintenance – cleaning of weekly and partly water changes are usually enough to get them to work in primarily condition. On the other hand, marine aquariums require more texture and regular monitoring of salinity, pH and nitrate levels for them to stay in balance. You need to spend more time balancing the environment and feeding the fish properly.
