Differences: plant cells have chloroplasts, central vacuole, cell wall. Paramecium is unicellular, motile.

… This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell.

What is the difference in size and shape between the onion and the Elodea cells? The onion cells are slimmer and smoother, but they are also connected (like bricks) like the Elodea cells. Elodea cells are more square and green and bigger. A cell wall, a nucleus, a cell membrane and a cytoplasm.

Elodea is a freshwater organism and should be kept in dechlorinated tap water.

Elodea provides shelter and food for many aquatic insects, crustaceans and fish. Elodea is often used in decorative purposes in the freshwater aquariums. Elodea quickly grows in waters rich in nitrogen and phosphorus. Rapid growth of elodea reduces oxygen content in the water and leads to fish kills.

Ecological Importance. Elodea provides habitat for many small aquatic animals, which fish and wildlife eat. Geese, ducks, and swans are particularly attracted to this plant. Elodea is an excellent oxygen producer and frequently used by fish to protect fry.

Elodea is an aquatic plant; submerge it into an established or de-chlorinated aquatic environment. It can grow un- rooted (free floating), however, it will grow more vigorously if rooted in a substrate.

Anacharis is not picky in terms of planting medium and can handle just about whatever is currently sitting in the bottom, including aquatic soil, loam, and even aquarium gravel.

Elodea Densa excellent oxygenating plant. The most popular aquarium/pond plant by far. This fast growing pond plants will do well in most situations. Just drop into shallow water (not deeper than 50cm) and watch it grow.

Many reasons such as :Newly planted, Used excel in tank, medicated the tank,changed yr ferts, changed ferts dosage, a changed in tap water or used RO, bright light/changed yr lights, etc.. Egeria Densa is sensitive to changeds in an aquarium and it reacts by melting.

Re: Why is my elodea densa turning brown?? Elodea, likes ‘Hard Water’. so is probably starved of calcium. If your running tropical temps in your tank then this is OK, but elodea will use more calcium with higher temps.

The presence of tannins is one cause of brown or yellow water that is usually not a problem. Tannins are present in driftwood, and over time they will leach into the aquarium water, staining it yellow to brown. Tannins lower the pH of the water and soften it. For some fish, this may be desirable and even recommended.

To clean your tank completely you need a gravel vacuum by your side. The gravel vacuum will gently pull out all the accumulated toxins, debris and solid waste products from your fish tank’s substrate and help maintain a natural balance in your fish tank.

You should do a 25% water change every two to four weeks. There is no reason to remove the fish during the water change. Make sure you stir the gravel or use a gravel cleaner during the water change.

The answer is that regular water changes are important for the long-term health of your fish. The dissolved wastes in the water, which are not apparent to the naked eye, won’t kill the fish outright, but the stress reduces their immunity to disease.

How to Tell If Fish Are Happy in New Tank?

1. Happy fish swim freely in all corners of the tank.
2. Eat most of the food because they have good appetite.
3. Mix with other fish and interact confidently socially.
4. Have bright colors.
5. Have spotless skin.
6. Are ready to breed.

Wildlife. In the Americas, where Elodea originated in the wild, waterfowl and water mammals eat the plant. Herbivorous invertebrates, such as snails, and native fish tend to prefer it as a habitat and eat it reluctantly.

Elodea can be removed by raking or seining it from the pond, but will re-establish from any remaining fragments and roots. Fertilization to produce a phytoplankton or algal “bloom” prevents the establishment of most bottom rooted aquatic weeds and produces a strong food chain to the pond fish.

Plant Description Elodea has branched stems with oval-shaped leaves arranged in clusters of three or four around the stem. The fruit of the Elodea ripens below the surface. Elodea produces heavy buds in the Fall that drop to the bottom and then begin to grow in the Spring; relying little on seed production.

Food. Commercial flake food is the best for guppies. Guppies can go without feeding over a two-day weekend if they are fed twice a day during the week. They can also nibble on the elodea or other aquatic plants.

Guppies are a freshwater fish, but you may not be able to use water straight from the tap. Chlorine is a problem for fish, so you need to use dechlorinated water. You could buy water for the tank, or you could use tap water and leave it in an uncovered container for 24 hours.

Yes, guppies need a heater. Sadly, guppies are often seen as a beginner fish that is disposable. Because of this, they aren’t always kept in the best tank setups or water conditions. Guppies are tropical fish and need to be kept in warmer water temperatures.

Why Guppy Swimming Strange at Bottom of the Tank? As a result, guppies may have trouble staying afloat and sink to the bottom of the tank. The most common cause is an enlarged abdomen or intestines caused by overeating or constipation. Other times, the disease can be caused by an infection or parasite.

The most common reason for guppies dying in your aquarium is the poor water quality. The lack of oxygen in the water can also cause guppies to die. Putting too cold or too warm water in your aquarium will cause death to your guppy fish. Tap water contains chlorine, which is deadly to guppy fish.

twice a day

Guppies usually have a tendency to take a bite at immovable or dead guppies. You certainly don’t want your guppies to eat a dead guppy as it would deteriorate their health. Also, dead guppies rot easily, and that will contaminate the tank water. This is not good for the other living guppies.

Guppies need light to thrive during the day, but constant light can actually kill them. Set your tank light on a timer so that it goes out and night and provides the guppies with time to rest and recharge. Provide hiding spots to reduce stress. To keep your fish healthy, they need to feel safe and secure.

Guppies do not have emotions like any other species of fish. So guppies do not die due to loneliness, but they can die if they get stressed. And that can lead to stress and eventually death. To avoid this, you can decorate the tank with plants to make your guppy feel comfortable.

Although I haven’t seen it happening in my aquariums, guppy males can kill each other and even other fish too, especially if these other fish are added later to the tank.

Male guppies can live together. However, guppies tend to breed a lot. In the absence of female guppies, male guppies can get aggressive and start fighting. That is why it is advisable to keep only male guppies together if you want to control the population of guppies in your tank.

They nibble on your fingers, but they are so small that their bites don’t hurt. Leave your hand in the tank long enough for your skin to get soft, though, and the guppies can begin to inflict damage.

So to conclude this article: yes, guppies and betta fish can live in the same aquarium. You will have a bit more work feeding your betta separately and you will also need to purchase live plants, but it is doable.

Betta’s are attracted to males guppies because of their pretty tails, they will kill them if they catch them, but in a big tank betta’s will act different, lots of times it throws them off and they are almost shy.

Yes, Neon Tetras are fin nippers in most of the cases. Even though they are delicate in nature, they are likely to chase each other. They also chase different fish fins that are in the same tank and nip the fins undoubtedly.

The signs of a happy, healthy, and relaxed betta include:

1. Strong, vibrant colors.
2. Fins are held open, but not taut, allowing their fins to billow and fold in the water.
3. Feeds readily.
4. Active, smooth swimming movements.

Can neon tetras die easily? Neon tetras can live up to ten years, but they can die easily with the slightest change in the fish tank environment. If there are any drastic changes in the water chemistry, the fish begin experiencing stress, depression and develop low immunity.

Do Neon Tetras Need Light At Night? No, they don’t need light at night as it can affect their circadian rhythm.

The 15 Best tropical fish for beginners are:

• Guppy.
• Molly.
• Zebra danios.
• Dwarf Gouramis.
• Bettas.
• Catfish.
• Swordtails.
• Firemouth Cichlid.

How Long Does Neon Tetra Disease Take To Kill. In most cases, it can take a week or two or up to a month or longer. This really depends on a lot of things but it really depends on when your fish was infected and how fast the parasite is growing inside your fish.

Cellular Structure As photosynthesis occurs, elodea plants pass the produced oxygen from leaves to stem. Some oxygen escapes from the leaves to form oxygen bubbles in the water but the majority escapes from the stem as a result of larger intracellular air spaces.

Leafy elodea was traded as an aquarium and pond plant. Unfortunately, it has escaped and causes problems including restricting water flow, increasing siltation, reducing aquatic plant and animal biodiversity, and interfering with swimming, boating and fishing.

Invasive Alien Species Regulation 2016. As of 2nd August 2017 Elodea crispa, Eichornia crassipes (Water Hyacinth) and Lysichiton americanus (Skunk cabbage) were banned for sale in UK. You are not banned from having these in your pond if you already have them but are required to take care to compost them well.

One of the few aquatic plants that provides underwater habitat during the winter months. Modest amounts of elodea are generally considered beneficial for the pond ecosystem. Dense growth of elodea can interfere with some uses of the pond, such as boating and fishing.

Elodea make for a wonderful introduction to the world of aquatic plants. They are easy to grow and, if cared for properly, look really cool. Just remember that their hardy nature also makes them an aggressive invader where they are not native. Never ever dump the contents of an aquarium into local water ways.

Elodea are fast growing aquarium plants, bunch them together to quickly start up a planted aquarium. Important note: The Elodea growth rate is fast. Elodea plants may quickly take over small aquariums and shade smaller aquarium plants.

Elodea canadensis belongs to a group of water plants whose soil roots produce root hairs while their water roots, under normal conditions, have none. Roots developed in water and in light are green and possess a cuticle. Those growing in darkness, whether in water or soil, have neither of these peculiarities.

Like other plants, elodea gets its energy from photosynthesis. Photosynthesis also generates dissolved oxygen in the water, which fish need to survive. Elodea may not thrive if your pond is in deep shade. Elodea grows in most soils but prefers a sandy sediment that’s rich in minerals and has a neutral pH.

Elodea grows very quickly and can reach a mature state within a week.

As Elodea spreads into new ecosystems, it experiences rapid growth for 5–6 years and then slows as soil nutrients are used up.

Propagation occurs really simply, by cutting a healthy stem off the main plant. Choose a long healthy stem, with plenty of leaves to take your cutting from and cut a stem which is at least 8 inches long. Trim the leaves from the bottom of the plant and then bury the off-cut 1-2 inches into your substrate.

However, while no CO2 is required, they do benefit from the addition of an iron rich fertilizer. Fertilizer should be added to the tank water on a weekly basis, and it’s usually best to add it after a weekly water change.

Why is my jungle Val dying? If it’s new to your tank, it is melting its leaves. They will grow back as the plant adjusts to your water parameters.

You can trim them but the new leaves will grow ~ as long. Leaf growth does not stop when it reaches the surface, making most vals unsuitable for many aquascapes.

You can use gravel or sand as a substrate for planting the plant in an aquarium. Ensure that the crown of the plant is not submerged in water.

Jungle val also does great in a beginners tank without dirt. I have seen it in low light tanks with hardly any sort of nutrients in the substrate. (If you want to have a great substrate, check out our dirt substrate kits) I have seen Jungle val grow in just plain sand even.

High lighting is the best option because Jungle Val would naturally receive lots of sunlight in shallow waters. They will survive in moderate lighting, but with a reduced growth rate. Aim to provide 8-10 hours of light a day. Fertilizer can be used to help growth, but it is not essential.

Val doesn’t need a lot of light to grow tall. Try some with root tabs and your current substrate, some with just gravel, sand, dirted, less filtration, no filtration, no UV sterilization, etc…
