Nexus Pure 15C

When you start this activity, the desire is to place the greatest number of fish, with the most different existing species.

Many beginner tanks have a high mortality rate, cloudy water and foul odors. In most cases, overpopulation in the aquarium considerably increases the amount of food needed and, consequently, increases the amount of waste in the water, which can lead to an increase in ammonia and nitrite, toxic compounds for fish.

There are an infinite number of possible fish combinations for each size of tank that we could recommend.

More Fish > Waste

Space – Ten 1cm tetras do not have the same body volume as a 10cm oscar. If your idea is to keep bigger fish, the amount of space becomes an important factor to consider.

Bigger Fish > More Space

Aggression level of your fish, ie, in African cichlids, the key is to add more fish and decrease the swimming space, so that no single fish has room to establish and defend its own territory.

Or a betta fish that lives in a community pond. Bettas tend to stay on top of the pond and can get aggressive if other fish are swimming close to the surface in their territory. In that case, you can choose tank mates that swim in the middle and bottom layers of the tank and that, for the most part, stay out of the way of the betta fish.

An aquarium is a living ecosystem and will change over time. Some species reproduce quickly and population booms can increase the waste load, so it may be necessary to remove fish to compensate. Healthy plants also grow over time, which reduces the waste load but reduces the available space.

First, having plants in an aquarium is not just a piece of decoration.

Natural plants bring many benefits. Fish are much more comfortable when we can simulate their natural habitat, just like us. In addition, plants also help balance substances in water.

Before starting a planted tank, it’s good to know what factors must be in place to ensure good results:

• Substrate – Where the plants will settle;
• Lighting – Installation of special lamps;
• Plants Protection Dosator – This type of product provides extra nutrients for plants.

Anubias:

• Maintenance: easy
• Substrate: no need (preferably fixed to logs/rocks)
• Lighting: low

It has broad, dark green leaves that provide shelter and protection for the fish. It is considered one of the natural plants for Betta aquarium, extremely resistant and easy to maintain.

Elodea

• Maintenance: easy
• Substrate: simple
• Lighting: low

A very resistant plant that resists even the least experienced aquarists! It’s a great haven for small fish!

Java Moss

• Maintenance: average
• Substrate: no need (preferably fixed to logs/rocks)
• Lighting: low

Versatile, Java moss is one of the most popular, hardy, and easy-to-grow creepers. However, fixing it can be tricky for a beginner. Use an aquarium fishing line or other materials that do not compromise the water balance.

For those who want to start this hobbie, the types of freshwater fish are the most recommended.

Aquarium maintenance is simpler compared to a marine aquarium, and fish are also easier to care for and maintain.

Goldfish or Goldfish

They are the most famous among the various freshwater species. This fish can live very well with another and, in addition, they do very well at room temperature, between 18ºC and 22ºC.

These fish eat a lot and, consequently, tend to defecate frequently, so it is important to test the parameters with the Water Test Strips, and proceed, if necessary, with the correct maintenance of the aquarium.

Guppies

They have a huge variety of colors and patterns, are resistant and reproduce very easily.

For people starting the activity now we recommend the Guppies. They live at 17-28ºC, and are compatible with Plati, Swordfish, Corydoras and Oto.

Avoid cichlids, as they are aggressive and fast and have a voracious appetite for smaller fish.

Tetra

Tetra are one of the most recommended if you want to have more than one fish in your aquarium. Resistant and showy, they live at 23-29ºC and in community.

Betta

The most colorful species, with very elegant tails and fins. We advise you to have this species, but be careful to mix it with other species.

Betta males do not usually get along well when raised with other males, as Betta females can get along very well with other fish, so find out from your shopkeeper the sex of this species if you want to pair with more fish.

1st Place the substrate (ask your shopkeeper for information about a good substrate);

2nd Place Sand and Water up to 1/3 of the Aquarium’s height;

3rd Place natural plants (check compatibility with your fish, ask the shopkeeper for information)

• When adding Natural Plants, also make sure the water is at a suitable temperature for them, and always plant the roots gently under the sand surface, leaving the crown exposed.
• Remember to keep natural plants moist until planted and to optimize root growth and development, use the Plants Protection Dosator and adequate lighting;

4th Place the decorations, but first wash carefully with warm water and never, at any time, use soap or detergents – they are highly toxic to fish;

5th Add the remaining volume of water;

6th Put the Fish Protection Dosator, to prevent diseases in fish;

7th Place the filter and consumables for filtration;

8th If you have species of warm water fish, we advise you to see this table and adjust the water temperature and measure it; (during temperature measurement, never place the thermometer near the heater, which could be misleading)

9th Turn on the filter;

10th Add the contents of the StartUp Kit, in order to prepare the water for your fish;

11th 4h after adding the StartUp Kit, you can add 1/3 of the most resistant fish;

12th After 5 days, you have to measure the water parameters, to ensure that your fish’s new house is in excellent condition, and for that use the Water Test Strips;

13th If everything is ok, add the remaining fish after 3 weeks;

1st – Place the Sand;

2nd – Place the Decoration, but before washing carefully with warm water and never, at any time use soap or detergents – they are highly toxic for fish;

4th – Place the Fish Protection Dosator, to prevent fish diseases;

5th – Place the filter and filtration consumables;

6th – If you have species of warm water fish, we advise you to see this table and adjust the water temperature and measure it; (during temperature measurement, never place the thermometer near the heater, which could be misleading)

Daily, if you have species that require it, check the water temperature
with the thermometer, and remember to always place it away from the Heater so as not to tamper with the results. Know now the care you should take with Water, Fish and Plants.
