Do you want that wild and awesome natural look in your aquarium? I sure hope your answer is YES! Well, if it is then, knowing how to keep floating plants in aquarium will do that for you. They’ll bring in unrivalled aesthetics; that is besides a host of other benefits. Just read on and I will explain how.
Floating aquatic plants vary both in sizes and shapes. Another unique trait of these floater plants is that most (if not all) have no attachment to the tank’s base. However, their roots are suspended in the aquarium water. These surface water plants literally sit on the water surface.
Why the floating water plants for fish tanks are important:
Below are five reasons why floating indoor aquarium plants are important besides decorating your tank.
Providing shade in the aquarium
These low light floating aquarium plants reduce excessive light penetration through to the water. Being surface water plants, they cut light rays reaching down the tank.
Shy pet fish species love it that way. It makes them feel “at home” and free as they roam the tank less exposed. As a result, this freeness subsequently reduces the stresses that come with uncomfortable exposure. Just so you know, stress kills fish’s immunity.
However, don’t let floater plants overly cover the water surface. This is because they’ll chock other aquatic plants, inhibiting not only their growth but also their survival.
That said however, ensure to match the intensity of cover to the requirement of other lives in the aquarium. Besides, floating aquatic plants are not for all pet aquarium fish; some love their habitat not shaded or well lit.
Providing cover and hiding spaces
Some fish species love to hide in the dark corners and caves in the tank. They are naturally shy and skittish.
Floater plants provide them with great hiding areas, especially floating aquarium plants with long roots.
They not only feel comfortable but also very secure hiding in the “safe spaces” under these plants. The effect is a great stress relief.
Helps with filtration:
Fish will naturally deposit waste in the aquarium water. In addition, dead matter as well as uneaten foods will also add to the waste.
Now if you leave the waste to decay, it will release excessively toxic compounds. One of such is ammonia which can easily poison your pet fish. You therefore need a filter to remove that waste. Here is how to treat your fish should ammonia afflict it.
Luckily, floating freshwater aquarium plants in the tank supplement the filtration system. How you ask? Well, a bacterium naturally develops on the roots of these live floating aquarium plants. It is this bacterium that breaks down these toxic compounds.
As a result, the fish are shielded from the incumbent risk of these toxins.
Fixing oxygen into the water
Really, do floating plants oxygenate the water? Yes!!! Just as plants release oxygen to the air, so do these floating freshwater aquarium plants to the water. They are a good compliment to aquarium air stones.
Your fish tank inhabitants need the oxygen to live. When oxygen is short in the tank, your pet fish will definitely suffocate. That’s besides the stress therefrom. You’ll actually see fish swimming near the water surface gasping for air.
Part of the fish diet
Duckweed aquarium plant is especially a great food source. Most other floater plats are loved by fish. They will spend time nibbling and snacking on these fast growing plants.
These plants are a good source of vitamins and other minerals. Subsequently, the fish is healthy and not exposed to nutritional deficiency related infections.
Criteria for picking floating water plants for fish tanks:
I hope you now appreciate the importance of the top water plants for aquariums. Now, in deciding which floater plants are ideal for your tank, you may need to consider a few factors. These include:
How fast the plant will grow:
First, fast growing aquatic plants will definitely need regular attention. Failure to do this, their invasive nature will make them engulf and crowd the tank unnecessarily.
Yes, plenty of them will help to aerate the tank besides managing nitrite and other toxins effectively. However, they could easily cause fish stress. This is if these floating aquarium plants inhibit their easy swimming.
For that reason, check out the growth rate of each prospective plant before deciding on which to stock.
How big is your fish tank?
Small plants are most ideal for small tanks. This is so if you don’t want uncontrollable vegetation crowding your small aquarium.
The vegetation should leave enough room for your pet fish to swim about freely. An overly dense small tank will make it very stressful for the fish to swim.
However, if you have a larger tank, you may choose to stock it with multiple but compatible fast growing plants.
Pet fish species stocked:
Pick appropriate floating aquarium plants depending on the likings of different fish species. If the fish thrive well in tanks with hiding places, then get floating aquarium plants with long roots. They provide a good shelter particularly for the fry.
Besides fish stock size, species also differ in their level of waste production as well as messing the tank. Therefore, rapidly growing easy floating aquarium plants will help reduce the effect of toxins. These plants are a good filter compliment.
The amount of light needed in the aquarium:
Low light floating aquarium plants will help dim sections of the tank where fish can take cover.
However, be careful not to affect the survival of other aquatic plants. If not well managed, floater plants will cut out much needed light for the other plant’s nourishment for growth.
