Hello fellow fish keepers, people on the fence about setting up an aquarium, or just some bored people who enjoy reading. Let’s talk about the three different types of freshwater fish, there ARE exceptions, but this is the real basic rundown. There are 3 different types, they are: “community” “semi-aggressive” and “aggressive “. I have what you would call a community freshwater tank. In a community tank the fish are generally small (except Discus and Angelfish), and one has the most options of getting a number of different fish in their tank. In other words, all of the fish are peaceful and all get along with each other (there are some fin nipping community fish to be aware of such as the Black Skirt Tetra, and Serpae Tetra, don’t house these fish with anything with a long tail.).Next we have “semi aggressive fish” which will just pester and nip a community fish to death if in the same tank, and “aggressive” which are usually big fish, that eat smaller fish, and even fish their same size, or they will at least fight one and other. An aggressive fish as a youngster, even though small, still has the same aggressive instincts as a grown one. Don’t let the size fool you, NEVER mix these three fish together. You can place a good amount of semi aggressive fish together, however when it comes to aggressive fish, your options slim down. It’s all about what you like. Some prefer a school of 25, 2 inch Cardinal Tetras and some Angelfish, some like 6-8 nice sized fish called Silver Dollars with some Rosy Barbs, some like a couple different 6-8 fish schools. Some like huge tanks with huge fish such as the Oscar. The options are numerous, that’s what makes this hobby so much fun. Remember, the bigger the tank, the more options you give yourself.
There are also African Cichlids, the most colorful of all freshwater fish, which can only be housed ONLY with other African Cichlids because of their temperament, and they just know they are with fish of the same, They get along with each other, kind of, they’re usually a little combative and territorial. To neutralize this you should “overstock” your tank some (put more fish in a tank than is usually allowed) with these Cichlids because it disperses their aggression amongst each other. You should also keep one male/three female ratio to lower aggression. There are three lakes in Africa (Lake Malawi, Victoria, and Tanganyika) that house these native cichlids, hence the name, and aquarists don’t like to mix fish from these lakes together. Some African cichlids are more aggressive than others, so do your research. You get the picture, if you’re not going to take the time and research, it could be a recipe for disaster. When you see these fish however, you will know why it’s worth it to read up on them, and get a tank going.
Left out are are Goldfish, I will be writing an article solely on them in the future,
Until next time, be good.
