If you are developing an aquarium, it is important that you have fish that are compatible with each other. If you have fish that are compatible, then you will have fewer problems in your aquarium. Here are the different fish categories so you can stock your aquarium with the same category of fish.

Categories Of Fish

There are three categories of freshwater fish that Aquarist use to identify fish that are compatible with each other. These categories allow people who are developing aquariums to select fish that will get along with each other. These categories are:

Community
Semi-Aggressive
Aggressive

You can look on the Internet for fish that belong to each category, but I suggest you go to your fish pet store to look for fish in each category. When I compared the Internet to the fish pet store, they were different. So I went with the way the fish pet store had them classified since I know they are professionals.

Categories

Here is how each category is defined:

Community – If you have community fish in one aquarium you have an aquarium called a Community Aquaria. That is a tank that has more than one species of fish. These are ones that require the same type of water and most important they have the same temperament. They are not aggressive toward other fish and are relatively peaceful.

When you select your community fish, select several of the same species so they can “hang” together. It is always best to select an odd number of fish of the same species, such as three or five.

Semi-Aggressive – Fish that fall into this category and are very active. They will also have aggressive action towards each other or other fish.

I have a 75-gallon freshwater semi-aggressive tank that contains Kissing Gourami, Three Spot Blue Gourami, African Featherfin Catfish and Tiger Barbs.

Aggressive – These fish are very aggressive and will harass fish of other species. They should not be mixed with other species but kept in a species only aquarium.

In general, do not mix fish of different categories in the same aquarium or you will have trouble.

Conclusion

When setting up an aquarium, it is important to know the different categories the freshwater fish fall into, before you buy your fish. If you do not know the categories, visit your fish pet store since they will have the fish divided into the different categories of community, semi-aggressive and aggressive.
