Having fish as pets is becoming more and more popular for a variety of reasons: depending on space and finances you can have the smallest of fish bowls to the most extravagant of aquariums, they can be very easy to look after and maintain or they can be very time consuming and expensive, they can also prove to be very relaxing; after all, who hasn't just sat and watched fish swimming around?

If you're looking to get an inexpensive pet for your children a small bowl with a couple of goldfish can be a great start. It can teach them responsibility, from ensuring the fish are only fed a certain amount at certain times to making sure the bowl is kept clean and the water free of algae etc. It can also be the best way to start learning more about fish before making the leap and spending what can be a great deal of time and money on a more expensive aquarium and all that entails.

If you decide you'd rather start a little bigger it's always a good idea to get as much advice and do as much research as possible as you're choices are really only limited to how much time and money you're prepared to offer. Often you can start with a ready made aquarium, that will provide you with all you need (excluding the fish) from the tank and stand, heater, filter, lights if required and all other accessories required to get your aquarium up and running.

Depending on what type of fish you wish to maintain: saltwater, freshwater, exotic to regular you will also need to thoroughly understand what is required for the health of your fish. Visit pet or fish shops to not only determine what you will need and what is required for each type of fish, but to also get an idea of how much it will cost to purchase such requirements on what can be a regular basis.

If you're intending on starting with a larger aquarium you will also need to know what types of fish can mix together along with whether or not certain fish require special food as opposed to others in the aquarium or other requirements such as correct temperature per certain fish types along with water types and balances etc.

All in all having a large aquarium, while it can look beautiful and will often be a major focus and talking point of your house, you need to remember there is a lot more involved than just aesthetics and if you're not prepared to put in the time and effort to maintain it, along with spend the money required you'd be better off sticking with something small and much easier to manage
