Is plants necessary in aquariums






Planted aquariums are fun! They offer a whole new dimension to the fish keeping experience. With freshwater aquarium aquascaping you can create an individual, one-of-a- kind, aquarium design. You will also be providing a natural balance to the aquarium and all sorts of benefits for the tank's inhabitants.

Why Start a Planted Aquarium?    Perhaps the most exciting aspect of keeping plants in your aquarium is the addition of a natural decor. Aquarium plants are very pleasing to look at and they offer hours of enjoyment for the hobbyist. With freshwater aquarium aquascaping you create a uniquely designed aquarium.
   For the fish and other tank inhabitants, aquarium plants provide many benefits. They create a comfortable 'homey' environment, they offer hiding places for fish, and they can serve as food source for a variety of aquatic animals.

Vital Functions of Aquarium Plants:      Having plants in aquariums is one of the most beneficial things you can do to make aquariums healthier, more stable, and simply more beautiful. Aquatic plants provide a physically enriched environment, but they naturally perform three other very important functions as well that help keep the planted tank in balance.

Aquarium plants produce oxygen
Plants go through two photosystems that are necessary to their survival. The first system is photosystem I, or photosynthesis, and is the most practical for the average hobbyist to understand.
Photosystem I:
   Photosynthesis is called 'light dependent'. Plants use several things in the process of photosynthesis to provide themselves with food and energy. These include light (normally sunlight), water, and carbon dioxide. During photosynthesis, oxygen is released as a by-product, which is then breathed in by the fish. It only occurs during the daytime (when sunlight is available), and so proper lighting must be supplied.

  "The other photosystem is called 'light independent', or otherwise known as the Calvin Cycle. It is not necessary for light to be present throughout the Calvin Cycle, although it is often coupled with Photosystem I. The net equation for the Calvin Cycle is: 3CO2 + 6NADPH + 6ATP -> glyceraldehyde-3-phosphate + 6NAD+ + 9ADP + 8Pi. This reaction is crucial to plant growth. The glyceraldehyde created is used either in the chloroplast in starch synthesis or it is exported to the cytoplasm where it is used in the synthesis of sucrose or other metabolites. The other products are used in continuing Photosystem I and the electron transport chain.
   "During photosynthesis oxygen is released as a by-product, which is then breathed in by the fish. Photosynthesis only occurs during the daytime however (when sunlight is available), and so proper lighting must be supplied."... Hannah Roberts.


Aquarium plants absorb carbon dioxide:
   Because they also absorb the carbon dioxide that fish breathe out, plants help keep the concentration of carbon dioxide in the water down. Plants also respire. This is the process of taking in oxygen and releasing carbon dioxide. This occurs continuously day and night.


Aquarium plants breakdown waste materials:
   Lastly, aquarium plants help in general maintenance of the water. They can help keep the water clean by absorbing waste materials emitted by the fish, as well as harbor bacteria on their surfaces that absorb waste material as a food source. Some plants can even keep the waste material on the bottom of the aquarium from decaying by emitting small amounts of oxygen from their roots.
   In all these respects, aquarium plants greatly improve the aquatic environment and enhance the survival of fish. Setting up a planted tank is fun, creative, and rewarding!

Live Aquarium Plants - Background Plants

Image
In an aquarium, background plants refer to those plants that are normally placed at the rear of the aquarium. These aquarium plants are usually taller plants with longer stems or leaves. They are placed at the rear of the aquarium for mainly two reasons. Firstly, they enhance the appearance of the aquarium background scene. Secondly, they he lp to conceal unsightly items such as filter tubes and heaters at the rear of the fish tank. Sometimes, these aquarium plants are placed at the front corners of the fish tank to the further enhance the overall appearance. Some common background plants are described below. Fanwort (Cabomba caroliniana) Cabomba caroliniana is a fine-feathered plant which is light green in colour. This aquarium plant looks stunning when planted in groups of three or more. It grows fast and lives well in bright lighti ng. It can grow up to a maximum height of about 50cm. Cabomba caroliniana is one of the most common species available and fairly easy to keep. An advanta

How to choose healthy fish

It's sad but true - not every fish is in perfect health. Here's how to pick the best of the bunch Here's How: Look at the top and sides of the tanks. If most are encrusted with residue, look for another shop entirely. Look for clear water. If it's discolored, avoid that tank. If the water in most tanks is discolored, look for another shop. Scan a half dozen tanks to see if any fish are sick or have died. If you see more than one sick or dead fish, find another shop. Avoid tanks with decaying plants, as the water chemistry is questionable. Do not buy fish that just arrived in the shop. They are stressed from travel, and might be carrying disease. Avoid fish with cloudy eyes, torn or clamped fins, and spots or sores on their body. Avoid fish that are sluggish or appear to be shivering. Look at all the fish in the tank. If any appear sick, don't buy a fish from that tank. Choose an active, alert fish. Take him home and enjoy your new pet. Tips

Breeding Guppies for dummies

Image
Guppies rarely need any encouragement to breed in the aquarium, but if you want to produce high-quality guppies it is a good idea to devote some time and energy to the process of breeding guppies. By carefully controlling the breeding process instead of simply allowing your fish to breed randomly, you can develop guppies with a much higher quality than what you would normally find in pet shops. Start out with high quality fish While the Guppy in your local fish store might be an excellent pet , chances of finding high quality guppies in ordinary pet shops are usually very slim. It is therefore advisable to contact a breeder and purchase high quality fish of the specific color and/or fin strain that you wish to breed. Purchasing from a reputable breeder is usually more expensive, but you will get a much better genetic material to work with. The breeding aquarium If you want to breed guppies, you should give them at least a five gallon aquarium. A fi
