Something important to be mentioned is that plants can bring many benefits and problems if they are given proper care. That is why we should select varieties suitable for the aquarium, so that these are not bitten and torn by our Gold fish. When this happens, pieces of leaf and stem can be introduced into the filter and may affect the filtration system. Now this does not mean it is impossible to maintain native plants in the aquarium. You can have success .. provided they are strong enough to resist the attacks of Gold fish. There are certain varieties of plants that meet this vital requirement for survival and which are listed below.
Should there be disinfected before placing the plants in the aquarium?
You must be careful to thoroughly wash the plants, because more often than is believed, are responsible for introducing bacteria and parasites to the aquarium, which can even lay eggs on leaves and stems. It is also recommended cutting some roots and remove dead leaves.
The way to disinfect plants is very simple. 5 liters of water are added 15 CC of vinegar and dipped plants and root around for 15 minutes, then rinse well with non-chlorinated water before placing into the aquarium. Another method is to use bleach (sodium hypochlorite in a very dilute composition) a ratio of 1:20 and dip the plant roots for 3 minutes. Other disinfectants may be used: bleach, copper sulfate and potassium permanganate. Not methylene blue should be used because this hurts them, so it is with chlorine.
Why does my Gold fish eat the plants I put into the aquarium?
The answer is simple: The Gold fish is an omnivorous fish, which means that feeds on animal protein and vegetable. Fish fed porridge and spirulina are less likely to eat plants, so it is advisable to add these two foods to your diet.
When Gold fish also likes eating the roots of plants, so it is recommended to bury and put small river rocks around the stem, so that they can not uprooted.
What are the benefits native plants to the aquarium?
Aquatic plants are important for optimal biological balance in the aquarium. They generate oxygen through photosynthesis and help reduce nitrate levels in water.
Aquatic plants need different nutrients for growth, one of which is nitrate. This is generated during the breakdown of harmful substances (fish feces, uneaten food, etc) by the filter bacteria and microorganisms.
Too much nitrate can be harmful, however. In high concentrations affects the health of fish and is the basis for the growth of nuisance algae. The plants consume a portion of the nitrate in the water for their growth and thus help to reduce the concentration of nitrate.
But the ability of aquatic plants to consume nitrate is not unlimited. If the concentration of nitrate in the water is too high, plants also get affected. With the regular partial renewal of water can keep nitrate levels in a reasonable limit.
Another benefit is that plants provide help to reduce the amount of algae in the aquarium because it will “steal” some of the nutrients that help its spread. Speaking of algae, it is important not to let this stick to the leaves, as it prevents the plant get nutrients from the water causing the leaves to wilt and die. Leaves can be cleaned periodically using only the fingertips, being careful not to scratch and damage the surface of the leaf. The cleaning is done without uprooting the plant to not abuse the roots.
What is the fertilization of plants?
Only healthy, well-developed plants can optimally fulfill its role in the aquarium. They need good water, adequate light and fertilization on time because not all the nutrients that plants need for growth are perfect in sufficient quantities in the aquarium.
Aquatic plants absorb nutrients through the roots and leaves, so fertilizers are marketed in two forms: pill (substrate) and in liquid form, which is added to each partial renewal of water. Fertilizers containing iron – a vital nutrient for plant growth – as well as other trace elements, which vary from one brand to another.
How important is light saves?
The lighting is even more important than fertilization. With poor lighting will be difficult to keep plants in the aquarium, unless you select varieties on request. Below is a list of recommended plants for aquariums, which describe whether requiring low / medium / or high illumination.
In the next section you can read more about the lighting in the planted aquarium.
What types of plants are there?
There are three types of plants, roots, and floating in clusters. Plants with roots tend to grow away from each other. The clusters are plants that reproduce easily when cutting the stems and they are buried. Floating plants have small roots and they discovered hanging in the water.
What plants are recommended for Gold fish Aquarium?
The following is a list of recommended varieties of Gold fish Aquarium. All plants that are common characteristics: stems and leaves are tough and are compatible with the parameters of the water present in the aquarium of Gold fish (hardness, pH and temperature). Now, this does not mean that all these plants survive the conditions for a Gold fish aquarium. Success is not guaranteed. Some people have Ceratophyllym demersum Elodea and in their tanks – I include myself in that group – while others say their fish eat the two varieties, leaving only the stems. It is best to buy a few and try different varieties to find those that are not palatable to fish … because fish like people have different culinary tastes
