Are tropical fish harder to keep than coldwater fish?
For the most part tropical fish create less waste and are generally more resilient than fancy goldfish and making them easier to keep. Many tropical fish are tolerant of a wide range of conditions, are small in size and very colourful making them ideal for the beginner or for smaller aquariums. However, this is not true of all tropical fish. Because of the great variety in tropical fish there are many that need very specific requirements and should only be considered by the experienced fish keeper after a lot of research. Always consult your local aquarium store before purchasing fish to ensure they will be compatible with anything you already have. If you are looking to introduce your fish tropical fish to your aquarium we would not recommend neon tetra (a very commonly available fish) but rather a more hardy variety such as a Danio .
