Fish Temperature
If you are having tropical fish you will need to have a heater in your tank set at the right temperature for those type of fish. So it is important to remember that not all fish come from the same part of the world and therefore some fish will require different temperatures than others. So you will want to choose fish that all live within the same temperature range.
Tank Size and Fish Size
The number of fish you have in your tank is quite important as you don’t want your tank to be overcrowded. You need to keep in mind that when you buy fish they are often young fish and are not fully grown, so think about how big those fish are going to get and then work out how many fish you can have in your size tank based on their fully grown size.
Not All Fish Get Along
All fish have different personalities and some breeds tend to be more aggressive than others so it is very important to take in their personality when putting different types of fish together. Some fish breeds will not only attack other fish but some will even eat other smaller fish. Fish such as Cichlids can be quite aggressive and so it is best to keep that type of fish together with others of the same type and not mix them with other types of tropical fish, this will ensure that you have happy fish that can live peacefully together.
Fish Diet
Different types of fish will have different diets. Some fish eat frozen food, others will eat flakes and others will eat live food. It is easiest if you stick to fish that eat the same type of foods and you need to learn how much to give them and how often to feed them.
So as you can see, choosing fish isn’t as simple as picking the prettiest one, you really do need to consider these other factors. If you aren’t sure about any of these factors then talk to your fish specialist at your local pet store and I’m sure they will be able to help you find the right fish for your tropical fish tanks.
