Aquarium without Filter

When you look at the list of items required to set up an aquarium, normally one of the items is filter. Why do we need the filter? The fish excreta is the harmful byproduct from the fish for the fish. The filter cleans the water of the tank by removing it. If so then can we setup an aquarium without filter?

Fish in Natural Habitat

Now if we look at the natural setting for the fish, what is it that cleans the water? Normally the natural habitat of the fish is river and ponds. In there is no filter. So how the water is clean and safe for the fish?

Natural Eco Balance

It is the nature where all is living in harmony. Rivers and ponds have the water flowing and it has vegetation. All these along with the fish reach an equilibrium and all thrive in this environment. This is natural Eco system in balance. The fish population is maintained in nature in balance and it helps to stop build-up of ammonia, nitrites, and nitrates making the water poisonous to fish.

Applying the Nature to AquariumPlanted tank

In aquariums the same can be achieved by duplicating the same natural habitat. What I mean is that we can have the fish tank planted. These natural plants use up the excreta of the fish as fertilizers and release oxygen keeping the water aerated.

When setting up a tank without filter, we have to consider the density and type of plants. At the same time the number of fish in the tank is an important factor.

Feeding the fish

Other than that we also have to be mindful of the amount of food for the fish. If we feed them too much then the fish will excrete more and that may be too much to handle by the plants.

Oxygenate the tank

Plants in the tank provide oxygen for the fish, They do this by a process called photosynthesis, where the plants take the carbon dioxide and release oxygen. This keeps the water oxygenated for the fish. For the photosynthesis process light is necessary. There are many types of lights available in the market for the plants.

Aeration of the tank

You will notice that many aquariums out there have a bubbler in there. That is to oxygenate the tank. But when you have the planted tank it provides the oxygen in the water, eliminating the need for the bubbler.

I have written an article about plants for beginners in the aquarium. Please read it to get an idea of what plants to use in the aquarium and their lighting requirements.

Water Temperature

Other than oxygenation of water and cleaning it of fish excreta we have to make sure that the water temperature is also suitable for the fish. Depending on of where you live and the weather conditions you may or may not need the water heater. All my aquariums are in the basement where it becomes very cold. So I have to use water heater in each aquarium.

Water Change

Other than the above steps make sure that the water change is done regularly. Especially a tank without filter needs that as there may be some harmful bacteria growth which may not be taken up by the plants. This can happen with too many fish in the tank.

Take away

As we can see that to maintain an aquarium without a filter is possible. Aquariums can be setup as planted with appropriate number of fish without filter. By providing the above mentioned environment we can enjoy the aquarium and fish will be happy.

5 Best Aquarium Fish

So, you decided to have an aquarium and now thinking “what is the best aquarium fish for it?”. The most popular is the 10 gallons aquarium. It is manageable and is suitable for many kinds of fish. You can place it on a countertop or a side table. Let us look at some of the fish which will be easy to maintain and add the beauty to your tank.

  1. Guppy  This is one of the fish which is very easy to maintain. They are readily available at most aquarium stores. They are great for beginners and are liked by many aquarium hobbyists.


They are very peaceful and live in planted and community tanks with no issues. They thrive well in the planted tanks with hardy plants such as Java Fern and Java Moss.

Guppies are live bearers and very easy to breed. Unless you are planning to breed, make sure you have only male or females in the tank. If you want to breed then make sure that you have another tank ready for the frys as the guppies tend to eat their frys.

It’s easy to distinguish between male and female. Male has more colourful and larger tail. It also has elongated anal fin as opposed to a short or fan shaped anal fin in the female guppy.


  1. Celestial Pearl Danio             This is another one of the best aquarium fish and easy to maintain. It was discovered in 2006 and has taken the aquarium industry with a storm. It is commonly known as Galaxy Rasbora.

Celestial Pearl Danio

They are peaceful and have very vibrant colours which make them not only popular among the new hobbyists but they add a different level of beauty to the fish tank.

They are schooling fish and prefer well planted aquarium. They are active and always moving around in the lower part of the tank.

Celestial Pearl Danio males show more vibrant colours on their tails and are slim. The females are slightly rounded and colours are little dull as compared to the males.


  1. Neon Tetras     Neon Tetras are also known as Neon fish. They were first discovered in Amazon jungles back in 1934. These fish are known for it’s dazzling colours and energetic temperament.

Neon Tetra

Neon fish thrives in well planted tanks along with driftwood and rocks. This kind of environment replicates their natural habitat of Amazon jungle rivers.

These are schooling fish and can be put 10 of them together in the 10 gallon tank if that’s all you are going to keep in there.


4. Black Molly     This is also called short finned or molly. This is a hardy fish which can adapt to survive from fresh water to saltwater with gradual acclimation.

Black molly

Black Molly are easy to care for as long as the tank is kept clean. There should be a weekly water change of 10 percent.

These are of peaceful nature and a great fish to keep in a community tank. They live peacefully with other fish mates.

Black Molly is a live bearer. So be wary of few things if you are going to have them. First make sure you have two to three females to each male Black Molly. Otherwise the female Molly will be harassed by the male. Keep similar ratio if you have more than one male Molly. Else the males will fight. Lastly make sure that when Molly gives birth, take the babies out to a separate nursery as the Mollies tend to eat them.


  1. Goldfish I am sure you have heard this name before and have seen them in aquariums. These are one of the most common and famous fish in aquarium field.


They are no doubt very easy to maintain and their colours are very attractive. Gold Fish breed varies in body shape, size, fin configuration and colours.

Goldfish are not live bearers and they lay eggs. The female lays eggs on the leaves of the plants.


Take away:    Keeping fish is a very satisfying hobby. You can sit and watch your fish swimming around the tank for hours (I love doing it). If you can handle little physical work, then it is a greatly rewarding hobby. As I have given the details on 5 different fish above, you can select anyone or two for your tank.

Make sure you are doing the regular water change and trimming the plants to keep the look attractive and fresh.

How to take care of Aquarium Plants

Today we are going to look at the topic of aquarium plants care. I am going to focus on freshwater aquarium plants.

Benefits of the aquarium plants

Plants in an aquarium not only enhance the look of the aquarium but it also helps to establish balanced Eco system in it and provide many benefits to your fish. By adding plants to the aquarium, we are trying to duplicate the nature.

What about artificial plants?

Some people add artificial plants to their tanks. This may be visually good, but it has fewer benefits than the live plants. I also heard from some hobbyist who have tried the artificial plants, that it takes time to clean the plants during the water change as there is a lot of algae sticking to the surface of these plants.

Natural is better

I prefer natural stuff in my aquariums anyways. In most of my tanks I don’t even have a filter. Some day I will write details of how I accomplish this. Today we are going to talk about Aquarium Plants Care.

Basics of aquarium plants care

Aquarium Plants care is not as hard as some people think. Follow some basic steps and you are on your way to have a planted aquarium which you will love and your fish will thank. Here are some basic rules to follow:

  • Select the plants suited to the kind of aquarium you have
  • Select the plants which are suitable to the kind of fish you have
  • When buying plants, you need to know what kind of substrate is suitable for them
  • Lighting is another factor to look at as well
  • Don’t forget that some plants require pruning

Some plants suggestion for beginners:

There are quite a few types of plants which anyone can grow in their aquariums. Here is a short list of them:

Java Moss:                                           Java moss

It is a great plant to use as carpet, front or back of aquarium or even to make a bonsai tree. This also provides microscopic food for shrimps.

Java Fern and Amazon Sword: Java Fern   Amazon Sword

These are easy to maintain plants and provides great hiding place for the fish.

Anubias Nana and Dwarf Sagittaria:

These are medium-sized plants and also easy to take care of.


I   hope that this short article shows that its easy to have plants in your aquarium. You can propagate these plants in your aquariums easily and can have fun in creating your own aquascape master pieces.


How to take care of Java Moss.

Today I am going to talk about Java Moss care. It is one of the easiest plant to take care of and the best friend of a newbie to aquarium field.

What is Java Moss

Java Moss belongs to Hypnaceae family. It is native to Southeast Asia. It is one of the most widely used plant in aquariums due to its ease of care and is very hardy plant. It clings to various surfaces so it is easily grown on rocks, pebbles, drift wood etc in the aquariums. Java Moss is very easy to maintain.

Java Moss grows outside and found by river banks, moist rocks and even on moist brick walls. It also grows easily underwater. It is used as foreground plant in aquariums or as a carpet plant. You can make underwater bonzai tree using Java Moss.

Benefits of using Java Moss in an aquarium

Java Moss not only adds colour to your aquarium but it also helps to:

  • reduce nitrates
  • reduce nitrites
  • oxygenate the water
  • Reduce algae growth

Lights for Java Moss

Java Moss care does not need any special lighting. It will florish in regular light. I have personally tried regular bulb, foresence light and LED lights. The results were great with all of them. I have not done a comparative study but overall I did not see any difference. Although it grows faster with brighter light, CO2 and fertilizers but it comes with a disadvantage of algae. Yes if you have too bright light then it will grow faster and you will also see algae growth on it.

I personally have all my tanks planted but I do not use CO2 or fertilizers. My tanks are made to mimic the nature with appropriate temprature, water flow and plants. I will write about them in the future.

Water Temperature for Java Moss

This plant is native to Southeast Asia and it thrives in tropical climate. Hence it loves the water temprature of 21 to 24 degrees Celcius (70 to 75 degrees Farenheit).

Trimming Java Moss

Since Java Moss is fast growing hardy plant, it needs to be taken care of by trimming it. If it’s left unattended can overgrow and the looks of the aquarium could be like a jungle instead of an aquarium.

The best way to do this is by using sissors and siphon at the same time. This way you are able to get most of the cuttings out of the aquarium. The cuttings outside the aquarium can be left immersed in water where it will grow. Make sure there is light for at least 8 hours a day for it to grow and thrive.

Taking care of Java Moss

Taking care of Java Moss is very easy. Once you get the moss (by mail or if you are getting from your local aquarium store) just attach it to the river rock, pebble or drift wood. Then immerse it in the water. The fish will also love it and it will enhance the look of your aquarium.

Once in the aquarium, make sure there is some light for at least eight hours a day. Now you have the planted aquarium to brag about. This will help to reduce small amounts of nitrates from the water and also absorbs some harmfull nutrients which encourage algae growth.

Don’t forget to trim the Java Moss occasionally to keep the look of your aquarium fresh.

Land Moss to Aquarium

Moss is one of the most interesting plants for aquariums. It is very easy to maintain at the same time very easy to propagate. It does not need any special lighting for its survival. Today I am going to share with you my experiment with land moss.

One day I was walking in my back yard and noticed some green patch. It was not grass and looked out of place and something algae. Upon close inspection it looked like moss which I had in my aquarium.  It got my curiosity so I scraped some from the ground and tried to wash all the dirt from it. There were no visible roots to it as was the case with my moss in the aquarium.

Land Moss
Land Moss

Since I was not able to get all the mud from it, I left it soaked in the water for couple of days. I made sure that the bottle was under regular LED lamp for about ten hours. I left it there for about two days. Then I took it out and washed it again. I checked it properly and there were no signs of stress or yellowing of the moss. So now I took a small piece of the moss and attached it to a river lock using plastic mesh. I placed this moss on the river rock in one of my aquariums.

This has thrived in there and grown so much that I had to trim it and now I have so much growth from it that I had to move the moss cuttings to a separate bottle.
