The two most commonly used cleaner fish are the lumpfish, Cyclopterus lumpus, and the ballan wrasse Labrus bergeylta. Lumpfish are distributed across the Atlantic ocean, ranging from Greenland to France, Hudson's Bay to New Jersey, and in high concentrations in the Bay of Fundy and St.

Geophagus translates to sand-sifter or eartheater. These fish will go to the bottom of your tank, grab mouthfuls of sand, sift through it, and then spit it out. This process will be repeated all day long.

In general, snails, shrimp, Otocinclus, the Siamese algae eater, and the bristlenose pleco are regarded as the best algae eaters for freshwater aquariums. However, you're most likely to come across and could be recommended a few other species, like Chinese algae eaters, common plecos, and Corydoras.

Siamese Algae Eater

Their downturned mouths are well-suited for eating hair algae, black beard algae, and leftover scraps in the fish tank. SAEs are known to tend to eat more algae as juveniles because the adults are big enough to get the lion's share of feedings in the aquarium.

The cleaner fishes of the wrasse genus Labroides (Labridae) are well known for their role in the removal of parasites from larger carnivorous fishes. The larger fishes recognize the cleaner fish and will not devour it.

While keeping shrimp is a very different experience than keeping tropical fish, they are great for keeping your tank clean from algae and food waste and they are fun to observe. These sociable creatures will definitely create an animated environment and they are quite easy to care for.

The shark and remora relationship benefits both species. Remoras eat scraps of prey dropped by the shark. They also feed off of parasites on the shark's skin and in its mouth. This makes the shark happy because the parasites would otherwise irritate the shark.

Mullet are commonly seen leaping out of the water. Why do they do this? Over the years there have been numerous theories concerning the leaping of mullet. There seems to be two categories of leaping: predator avoidance and aerial respiration.

What gets rid of fish poop in tank? ›

Vacuum the Gravel Fish feces, shed scales, uneaten food, dead bits of plants, and other debris will settle to the bottom of your tank. Vacuuming the gravel every week will remove much of this debris and refresh the tank, brightening the gravel and keeping the tank healthier.

Otocinclus catfish, stiphodon gobies, and bristlenose plecos are the best algae eaters for cleaning your glass. Mystery snails and nerite snails are great invertebrate options for keeping your glass free of algae.

Purely marine animals, there are no freshwater sea stars, and only a few live in brackish water.

Chlorine is still one of the most effective killers of algae so doing a super-chlorination of 10-20 ppm of chlorine can go a long way towards wiping out the algae. Liquid chlorine is an ideal shock for algae because it is fast acting and does not add cyanuric acid (CYA) or calcium to the water.

Barley straw. Barley straw is a natural way to fight algae. On contact with water, the straw starts to break down, and as it does so it releases peroxides into the water which combat algae. Available in mini bales, or as a concentrated extract of barley straw liquid, it's a natural way of chemically fighting algae.

Change the water regularly to keep nutrients low and if you have plants, use a liquid fertiliser to actually strengthen the plants and help them to fight off algae naturally. If the tank contains no live plants then you can use nitrate and phosphate resins to soak up those spare nutrients and starve the algae.

The best method to remove green algae is a UV light. This will zap the algae in suspension continuously and not harm your fish in any way.

Every tropical tank needs a catfish! They help keep the tank clean by eating algae and, as they are bottom feeders, will also eat any food particles that have remained un-eaten by the other fish in the tank.

Species of large tuna that are considered free of parasites include: Albacore, Yellowfin, Blackfin, Bluefin, Bigeye, Longtail, and Karasick. Fluke, Grouper, Jack, Bass, Trout, small Tuna, and Salmon (aquacultured and wild) may contain parasites and should be frozen for parasite destruction.

What is anisakiasis? Anisakiasis, or herring worm disease, is a parasitic disease caused by nematodes (worms) that attach to the wall of the esophagus, stomach, or intestine. The best ways to prevent this disease is to avoid eating raw or undercooked fish or squid.

How many shrimp do I need to keep my tank clean? ›

Shrimp are very small and have a lower output of metabolic waste than fish, so they can be kept in smaller tanks/more densely populated conditions. With that said, I wouldn't push it; it is best to do a maximum of 10-15 shrimp per five gallons.

Before you begin.

It's best to keep your fish in the fish tank when you clean. Removing them causes unnecessary stress for your fish, and you run the risk of accidentally hurting them. It is possible to keep your fish in the tank while you clean because you don't need to remove all the water to clean the tank properly.

Almost all freshwater snails are beneficial scavengers that eat algae, dead plants, dead fish, extra fish food and other waste. This cleaning ability makes them an outstanding addition to your freshwater tank.

Sperm whales have been cut open to reveal entire sharks and squid that had been swallowed whole, as well as other flotsam. Their jaws aren't designed for “chewing”—thus, they are adept at swallowing whole prey.

Remoras — also known as suckerfish or whalesuckers — are strange, even for fish. They hitch rides with cetaceans, sharks and other larger creatures of the deep, attaching to them by means of a “sucking disc” that sits on their head like a flat, sticky hat.

In conclusion, fish don't get thirsty like humans or other animals. They have evolved to live in water and have adapted their bodies to regulate the salt and water balance through osmosis and special cells called ionocytes.

That's most likely a mullet. Mullet (Mugil cephalus) are common jumpers and there are several theories about this behavior. Some scientists believe they leap from the water when pursued by predators.

Life of an African lungfish

To manage this life-threatening situation, the lungfish secretes a thin layer of mucus around itself that dries into a cocoon. It can live out of water in this cocoon for up to a year, breathing through its lungs until rains refill its waterway.

Well the good news is, fish poo should provide all the nutrients your plants require in any aquaponic system. The bad news is, if fish poo is allowed to accumulate it will almost certainly eventually kill your fish. It's all a matter of balance – once again! Fortunately, it's a balance that Nature helps us achieve.

Where do you put fish when cleaning a tank? ›

Use a small bowl, mug or cup that has been thoroughly rinsed with distilled water as a temporary tank. Never place fish in containers that have been washed with soaps, as even a small amount of residue can be toxic. In a pinch, you can also use a large plastic zip bag.

Constipation in fish is typically revealed by bloating and the production of stringy feces. Normal fish feces will immediately fall to the substrate; constipated fish feces will appear stringy and hang from the fish.

You may even have searched for fish that clean the tank. In freshwater aquariums, “Plecos” (short for plecostomus and used to refer to fish of the family Loricariidae) are one of the most common fish purchased to aid in algae cleanup.

The most widely known rule for stocking a tank is the one inch of fish per one or two gallons of water rule.

Going by the numbers, however, you can put up to 8 to 10 fish in a 10-gallon aquarium tank. However, we would not recommend adding 10 fish in a tank unless the fish are tiny and do not generate too much waste. On the other hand, if you have chosen fish types that grow over time, you should limit the number to 8 or 6.

Seahorses are primarily marine fish, although a few species have been found living in brackish rivers. The seahorse occasionally sold as “freshwater seahorses” are actually freshwater pipefish. These are related to seahorses, but true seahorses cannot live in fresh water.

Despite some fun legends about giant lake octopuses, there's no such thing as a freshwater octopus. And that's because octopuses' bodies are built for saltwater, and no known octopus species in the very long history of octopus species have adapted to live out its life in freshwater.

FRESHWATER SQUID DO NOT EXIST, ALTHOUGH THERE ARE FRESHWATER SEALS IN LAKE BAIKAL.

Jill put a squeeze of Dawn liquid soap in a bucket and filled it about halfway with water. She dunked her car wash brush in and went to work. Jill says that she barely had to scrub it. The Dawn took the algae right off.

Chlorine is the only chemical that acually kills algae. It acts in the same way as setting fire to the algae, it oxidises it. When you have a bloom of green algae in your pool then by far the best thing to do it to blast it with a shock dose of unstabilised chlorine.

What does vinegar do to algae? ›

If you have an algae problem, your best friend is white vinegar. White vinegar can quickly kill algae but is not harmful to birds, insects and the majority of plants. Use a mixture of one part water to one part white vinegar to spray down the area and kill the algae.

Perform water changes: The single most important way to avoid algae is to perform regular water changes. Change 10 to 15 percent of your aquarium water every week to lower nutrients in the water. This will remove the nitrate that accumulates in aquariums, which is one of the main fertilizers for plants.

Zooplankton, tadpoles, and crustaceans eat algae. Many aquatic consumers such as zooplankton, tadpoles, algae eater (algivore), small fish, crustaceans, and water-dwelling insects eat algae as their primary food source.

Causes of Algae in Aquariums

Too much light or too many nutrients in the water will cause algae to grow rapidly. If you experience algae overgrowth, it could be caused by: Leaving house lights on too long. The tank receiving too much direct sunlight.

Amano Shrimp (Caridina multidentata)

These guys are some of the best algae eaters around. They are known to eat most types of string and hair algae, such as the commonly found green hair algae. Some hobbyists claim they can even tackle the dreaded black beard algae, making them perfect additions to planted tanks.

Do You Need an Algae Eater? There are many ways to control algae in the tank, and you do not necessarily need an algae eater to combat the problem. Because an algae eater means one more fish or creature in the tank, its needs have to be considered as well, and it may be best to control the algae in other ways, such as…

Many freshwater tropical fish are great algae eaters in their own rite. Livebearers including Black Mollies, Fancy Guppies, Platys, and swordtails eat string algae and sometimes white beard algae. Guppies and Endler's Livebearers also do a number on the green algae in a tank.

What is the name of the fish that suction to glass? ›

Plecos attach themselves to hard surfaces with specially adapted mouthparts. They are scavengers and will eat almost anything! Great for beginner hobbyists in a community tank. Plecos spend most of their time on the bottom or sides of the aquarium and are most active at night.

Almost all freshwater snails are beneficial scavengers that eat algae, dead plants, dead fish, extra fish food and other waste. This cleaning ability makes them an outstanding addition to your freshwater tank. Freshwater snails also come in many colors, shapes and sizes.

The tiny cleaner wrasse will go right into the larger fish's mouth or gills and remove parasites and mucus right off of the sharp teeth, much like our human dentist uses a dental pick to clean plaque off of human teeth.

When pilot fish are young, they gather around jellyfish and drifting seaweeds. Pilot fish follow sharks because other animals which might eat them will not come near a shark. In return, sharks do not eat pilot fish because pilot fish eat their parasites. This is called a "mutualist" relationship.

People who fish for a living see the darnedest things.

Like this mammoth grouper, that looks like it's from the Stone Age, come from deep to devour a reef shark whole in one swallow.
