Top 10 Aquariums tips

Guppy Fish

The Guppy is a popular breed among new aquarium enthusiasts, because it doesn’t need too much special knowledge, to care for it. All you need for it, is a simple freshwater tank, with multiple plants and substrate. Their natural habitat is in South America, where they were first found in 1866. You may also know the Guppy, as the Million Fish or the Rainbow Fish. This species comes in many different colors and variations. You’ll find red, grey, blue and many other versions on the market. Their tail shape is also different, depending on their type. One thing is common though: every Guppy looks beautiful in a community tank. Usually, Guppies are peaceful fish, that are good to be kept together with other species. They will swim around all day (usual behavior). If you find them sitting in a corner, or not moving for a fairly long period of time, they could be sick or stressed out.

Platy Fish

The Platy Fish, is another great choice for beginner fish keepers. It is a breed, that you can care for easily, and looks great in pretty much any community tank, due to its peaceful nature. It can live up to 5 years, if you do everything by the book. Also, most Platies will grow up to 3 inches long, so they’re not very big. Like the Guppies before them, Platies also come in many different colorations, so you’ll have plenty of choices. Most Platies are considered omnivores, so they eat plants and meat as well. However, be balanced when you set up their diet. Usually, vegetables need to be the biggest part of their diet, with some additional meat components. In their natural habitat, they eat all sorts of things, but like most of all herbivorous food. To make your Platies happy, keep the aquarium full of plants, where they can hide and live their life, like in their natural environment.

Molly Fish

The Mollies are a great choice for both beginner and veteran fish keepers. They are easy to care for and also, any Molly will look great in your freshwater tank. Usually, Mollies are community fish, so they will behave peacefully, when kept together with others. However, if their tank mates aren’t peaceful enough, Mollies could start behaving more aggressively towards them. So, make sure you only keep tank mates that behave peacefully, to avoid any conflicts. Just like the Platies before, Mollies are also omnivores, so you can give them all sorts of food. Worms are a good choice, but don’t stop there. Mollies really like to eat algae and simple vegetables as well. You can even give them vegetables from your kitchen. Only make sure, you cut those into small pieces, for them to be easy to consume. Mollies are small fish. Most of them won’t grow larger than 4,5 inches long. Because of this, you can put multiple ones in the same tank. This way, they will feel much more at home. If you care for them properly, they live up to 5 years.

Swordtail Fish

Swordtails are a big family of fishes, because they come in a multitude of different colors and shapes. However, a common aspect of Swordtails, is the sword-like tail, present at all versions, hence their name. They are very popular, because you can care for them easily, without much of a headache. What do they need? For instance, a 15-gallon aquarium is a good starting point. Swordtails won’t grow too big, however they swim around a lot. So, having such a tank will benefit them quite a lot. Also, it can be a good idea to cover your tank, because Swordtails are great jumpers. The water temperature should be kept between 65- and 82-degrees Fahrenheit. To make sure the temperature is always in their favor, avoid sudden changes. Feeding them is quite easy. You can buy flake food, but simple vegetables will also do the trick. They like worms and shrimp as well.

Cory Catfish

The Cory Catfish, or Corydoras, is a very popular breed among freshwater tank owners. One of the main reason, why so many people own one or more Cory Catfish, is that they eat a lot of algae. Actually, the Cory Catfish is used as an aquarium bottom cleaner fish. Most of its time, is spent scavenging the bottom of the tank for left-overs, and most of all, algae. Actually, a single Cory can clean a 20/30-gallon tank by itself, from all the algae in it. Of course, it’s best if you keep multiple ones in your aquarium. They are community fish, that live peacefully with most other species. Most Corys will be active during daytime, but it happens quite often that they remain active in the night as well. If you plan to keep Corys, know that they need a 10-gallon tank, at least. They can thrive in bigger aquariums as well, but a 10-gallon tank is fine in most cases.

Bristlenose Pleco

The Bristlenose Pleco, is a very common Pleco Catfish species, that people tend to choose over the Common Pleco, because of its smaller size. Usually, a Bristlenose Pleco will grow up to 5 inches long, which is a lot smaller than the Common Pleco, that grows up to 24 inches. Even so, this species needs a lot of space to thrive in. If you plan to buy Bristlenose Plecos, make sure you have an aquarium that is 25 gallons in volume. Also, you should know that keeping 2 males in the same tank isn’t a good idea. This version of Pleco Fish, is quite territorial. Two males in the same tank will feel threatened all the time by each other. So, it’s best to put 1 male and multiple females in your tank, if you want to have more than one. Like the Cory Catfish, the Bristlenose Pleco is also a bottom dweller. Most of its time is spent on the bottom of the tank scavenging and eating algae. However, besides the algae from the tank, they will need to have a vegetarian diet, composed of sinking pellets (wafers) and simple vegetables.

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.


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.


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.

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.
