Purchasing Fish For Your Freshwater Aquarium

1.) As a home aquarium owner wanting to purchase freshwater fish, there are a few things you must remember; of this, the most important is that you know which kind of fish you want to keep and the other species that can stay together with them. The size of the aquarium determines how many fish you can keep comfortably in it - go by the simple thumb rule of each fish requiring at least 3 inches in each gallon of tank water so they can discover and grow naturally. Freshwater aquarium fish only grow as big as the space granted them, so you know that the more space you give them in tank water, the longer their lifespan will be!

2) Know your fish species: especially for the freshwater aquarium set up you have, in order to determine which are the types that can live in captivity, along side other varieties and the kind of tending they require in order to grow and breed. Also take the time to find out the kind of tank environment will suit the kind of freshwater fish you are keen to buy, the kind of temperature preferable to them and the food they will be eating as apart from compatibility, these factors also influence the health of your tank inmates.

3) When buying fish for your non-marine aquarium, keep in mind any advantages you can give the tank fish you purchase in terms of investing in fish that consume algae so the build-up does not affect the maintenance of the tank and makes less work for you.

4) Last, but not least, when considering buying fish for your freshwater tank, it is important to know which are the species to avoid buying that can be unfriendly - to say the least - after all, you do not want the fish in your home aquarium to live in an environment of disharmony, do you? So, learn as much as you can about which kind are territorial e.g. Catfish that can also grow big in a short time and eat into the space required by others in the tank. Also avoid buying the dangerous or poisonous kinds of fish harmful to keep in a freshwater aquarium, such as Piranhas since these can disease easily and also intimidate the other fish in the tank, which is an expense you want to avoid if you want to keep your fish happy, healthy and for a long time.
