How do you decide which tropical fish is best for you? An important factor while buying tropical fish is its color. Another factor is that lots of people purchase sick fish. It is very easy to notice if the fish is sick, most of sick fish refuse to eat. Don’t be coy and ask the seller to feed the fish before you put your money on it.

There are few rules we should remember while we keep our freshwater or saltwater tropical fish, first rule is to be patient.

Keeping freshwater tropical fish is the ideal starting point to this rewarding hobby and can be done so by almost any age group, even children (best start with the family), with limited supervision.

One advantage of keeping and/or raising freshwater or saltwater tropical fish is the large international community that shares your interest.

Fish tanks are a wonderful place to observe a habitat on a smaller scale. Tropical marine fish enjoy their temperature a little bit warmer at 80 to 82 degrees Fahrenheit (26C). Tropical fish are very colorful and therefore very popular as aquarium fish. Tropical fish tanks have to be constantly monitored for presence of harmful bacteria, fungi, and algae.
