Aquariums tips

Rainbowfish

The Rainbowfish is a popular breed, both among beginner and experienced fish keeping enthusiasts. They are small fish, that live well together with other community fish species. Because of their small size, you should avoid putting bigger fish in the same tank as them (Bettas for instance). They are schooling fish, so make sure you have 5 or 6 at least in a group. This way, they will feel at home in their new environment. If you keep multiple ones together, the males will exhibit their best colors towards the females. The group will look much better because of this. Feeding them is pretty simple, since the Rainbowfish are omnivores. You can give them earthworms, pellets, simple vegetables, or specially made food for their kind. However, they are not bottom dwellers, like others on this list. Make sure, they have plenty of space in the aquarium, because they like to swim around in groups. Usually, a 30-gallon tank is enough for a group of 6 Rainbowfish.

Danios Fish

The Danios are a bigger family of fish. They come in many different versions. Some of the most popular ones are these: Zebra Danios, Pearl Danios and Queen Danios. Now, let’s take a look at the Zebra Danios, more closely: You need at least a 10-gallon tank for housing Zebra Danios. They grow up to 2 inches long, so they’re not the biggest among fresh water breeds. Being so small and peaceful, makes them great choices for community aquariums. Differently from many other species in this article, the Zebra Danios will thrive in colder waters, just as well as warm ones. Most Danios need a water that’s between 64- and 75-degrees Fahrenheit. So, you don’t need a water heater, to keep Danios in your tank. But a great water filter is a must. They need a crystal clean water, to thrive in. Make sure you buy a cleaner that does a good job at this.

Otocinclus Fish

The Otocinclus breed, is another fish, that is well-known for its algae eating capabilities. Because of this, feeding them will be quite easy, similar to the Siamese Algae Eaters. There is a difference however: The Otocinclus Fish, is an herbivore species. So, avoid giving them meat, or other food products that include meat as well. A good choice, would be the algae wafers you can buy at any fish store. Usually, 1 piece at every 2 days is enough to feed them. But if you don’t want to buy ready-made food, you can get something from your kitchen too. Green vegetables are loved by the Otocinclus. Lettuce, spinach and zucchini are great, if you cut them into small pieces. If you have a tank of small, fresh water fish, the Otocinclus can prove to be a great addition. Due to its peaceful nature, it will thrive with other peaceful species in a community tank.

Siamese Algae Eater

The Siamese Algae Eater, like its name suggests, is most commonly known for its algae eating capabilities. Most people who add this breed to their aquarium, do it because this species will clean the tank from most of the algae. If you want a fish that works well with most other breeds, the Siamese Algae Eater is a great choice. It is a peaceful species, that lives well in community tanks. Because it’s a bottom dweller, you need to make sure, the others who will live there, don’t bother your Siamese Algae Eaters. Also, it’s worth mentioning that Algae Eaters live well in groups of 4 to 6 members. Usually, they like to school together, but this isn’t a must. If you want to, you can keep only 1 or 2 of them in the tank as well. They thrive, no matter their numbers. They are omnivores, so feeding them will be quite easy. They will mostly eat the algae that in the water, but you should give them other food supplies too. Pellets and wafers that sink to the bottom of the tank, are a good choice.

Betta Fish

This species is a controversial one. On one hand, it is a very beautiful and sought for fish, that even beginners would like to own. On the other hand though, it is quite complicated to care for, thus making it a tougher choice for beginners. First of all, everyone would like to own 1 or 2 Bettas, because of their special look. They come in many different colors, but the most important aspect when you look at them, is the fin in the back. This covers half of their body, making them look very special, compared to most other species on this list. But being among the most beautiful fish, comes with a price: they rarely get along with others. Usually, Bettas hardly get along with each other. Because of this, adding other species to the tank should be done carefully. Some good tank mates could be the Black Tetras, Catfish, Croacking Gouramis, Rasboras and Poecilias.

Rasbora Fish

Just like the Tetras before, the Rasbora is another bigger family, that consists in many different versions of the same species. Some of the most popular Rasbora Fish are these: Harlequin Rasbora, Brilliant Rasbora and Clown Rasbora. The Harlequin Rasbora Fish is well-known among fish keepers. This one lives in small groups, and likes to meet other tank mates frequently. Also, it is one of the most simple to care for species among the others on this list. Basically, the Harlequin Rasbora is the perfect match for a beginner fish keeper. If you make sure they have a clean water, together with a balanced diet, they will surely thrive in your artificial environment. And it’s worth mentioning that a Rasbora will live up to 8 years, if you do everything by the book. Be sure to put small fish in the same tank with Rasboras; at most, fishes that are double in size. Otherwise, bigger species will see them as a snack.

Tetras

The Tetra Fish, is a big bunch of different versions of the same Tetra species. For instance, these are some of the types of Tetras you can get from a store: Neon Tetras, Rosy Tetras, Lemon Tetras, Penguin Tetras and other as well. One of the most commonly bought versions, is the Neon Tetra. This is a very small fish, that grows only up to 1.5 inches long. Even so, it is among the most beautiful freshwater fish you could get. And on top of that, it lives up to 8 years old. They like to school together, and most of their time is spent swimming around in the tank, especially in the water column. Because of their peaceful behavior, they are the perfect addition to a community aquarium.

Angelfish

The Angelfish is among the most beautiful species you can get for your freshwater aquarium. It comes in all shapes, sizes and colors. The Angelfish is naturally spotted in South America, in many rivers, including the Amazon. They slow moving water, that is full of driftwood and other great places for hiding in. Because of this, your tank must also contain these elements. For hiding places, you can even put small caves in the tank. The Angelfish is an omnivore species, so you can feed it with many different food items. For instance, they really like worms and flakes, that are specifically made for them. However, you can also feed them simple vegetables, that are sliced into small pieces. Be aware that fully grown Angelfish, could eat smaller fish that are present in the tank. This doesn’t mean that they are aggressive. They just simply eat almost anything that fits in their mouth. So, keep this mind when you choose tank mates. It’s best to have mates that grow as big as these fish.

Gourami Fish

The Gourami is another bigger family of fishes. There are many different versions of this species, that most work well in freshwater indoor aquariums. If you plan to buy some of these, depending on the type of Gourami you buy, you’ll need a bigger or smaller aquarium. For instance, the Dwarf Gourami, is a small version, that will live happily in a 10-gallon water tank. But there are others, that grow way bigger, and could need an even 30 or 40 gallon tank. Something common with all Gouramis, is the fact that they like a well-planted aquarium. So, make sure your tank is full of tall plants, that touch the surface of the water. This will make them feel at home. Also, keep in mind that males don’t like each other; they quickly become aggressive towards one another. So, keep only one male in the tank, with multiple females.

Killifish

Killifish owners are among the largest groups of fish keepers on the globe. Why? Because the Killifish is one of the most beautiful looking species that you can get for a fresh water aquarium. There are many different types of Killifish that you can buy, but there is something common in all of them: they are all vividly colored. Almost all types of Killifish are peaceful towards other breeds, which makes them  great tank mates to almost every community fish species. However, the males could get aggressive against the other males in the tank. Most Killifish breeds are carnivores in their natural habitat. To feed them properly, you can give them crustaceans, insect larvae and worms. These should all be live when you feed your fish. Killifish require a well-balanced diet, to meet their nutritional requirements. Such a diet includes the following food types: Brine Shrimp, Daphnia, Mosquito Larvae, White Worms, Black Worms and Tubifex Worms.
