Big things do come in small packages…small pieces of jewelry, small tokens of appreciation from friends, and yes, even small pets. Tiny animals of the scaly kind are a good idea if you fancy looking after a small pet. The popular pet choice which belongs to this category would be a goldfish. They are easy to care for, and don’t 
eat up too much space. Not to mention, you won’t find any stray hairs or fur on your living room couch! Sure, it may not be as popular as its cousin Nemo, but it is sure to give you lots of fun nonetheless.
When you come home from the pet shop with your new pet goldfish, don’t just dump it in the fish tank. First let the chlorine from the water evaporate by letting it stand at least overnight. It’s also more advisable to use a rectangular fish tank rather than a fishbowl, as the former gives the goldfish more space to move. This movement aerates the water, making it a healthier swimming environment. It wouldn’t hurt to put a tightly-woven wire mesh over the tank, to keep your fish from accidentally jumping out. Hey, even fish get excited too!
Keep the aquarium away from sources of heat. Too high temperatures can cause oxygen deprivation, which needless to say, could be fatal for your little friend. Change 10-15% of the tank water every week to make sure that your goldfish swims in waste-free water. Adding a filter to the tank helps clean out any waste that may be left behind.
When it comes to feeding your goldfish, you can start off with pre-packaged fish food. Choose those which are made especially for goldfish, as this will have the right balance of nutrients for them. Be sure to feed your goldfish at least twice a day. And all the food should be eaten in five to ten minutes, as any leftover food would mean you are overfeeding it. These food scraps, when left in the water, could pollute it and make the goldfish susceptible to illness.
Goldfish are small pets which can be good companions for a long time. Make it a habit to watch your goldfish a few hours everyday, so you can pretty much get an idea of its daily habits. If you sense or spot anything unusual, better take it back to the pet store so they can help you.
