Do cory catfish play with each other?


Why is there no oxygen in my tank?

Water Movement. Stagnant water will have lower oxygen levels. This is particularly true lower in the water column, where no oxygen exchange is occurring. Water at the surface will have more oxygen, but because it’s not circulating sufficiently, that oxygen doesn’t reach the lower portion of the tank.

What are the symptoms of an air bubble infested fish?

The fish (especially the Balas) have what appears to be little air bubbles all over their skin. The large CAE looks discolored. Even the knife fish looks as though he may have air bubbles on him. They all seem a little more lethargic than normal.

Why does my filter have bubbles in my water?

Hanging filters can also cause bubbles to form. Put simply, if the bubbles pop shortly after forming, don’t cover the entire surface of the water and don’t appear foamy, then they’re probably nothing to worry about. According to Petcha, some species of fish create bubble nests.

Why does my fish tank have bubbles in it?

The most common occurrence is a fish tank that is not filled to the top. The impact of the water from the waterfall mixing with the lower water can also introduce bubbles of various sizes. The bubbles may vary depending on your water temperature and bioload.

How can you tell if a fish has gas bubbles?

Sometimes “candling” fish in a strong light helps to spot gas bubbles, but these can be hard to see, even histopathologically. Mortality rate varies with the age and species of fish involved. Figure 3.

What causes gas emboli in fish?

Most gas emboli are produced by excess nitrogen because oxygen is assimilated metabolically and thus less likely to form persistent bubbles. However, very high oxygen levels are dangerous. When fish breathe supersaturated water, the excess gas can form emboli in various tissues.

What does bubble disease look like in goldfish?

Bubble disease is not really a disease at all. Goldfish affected by supersaturated gases might show symptoms such a s uncontrolled swimming; gasping at surface; bulging eye, known as pop eye, bubbles escaping from mouth or gills; raised areas that look like tumors, which are actually air pockets or bubbles under the skin or bubble disease; not r…

What does a bubbler do for fish?

On its own, a bubbler performs two helpful functions: [ 2] 1 Aerate the water#N#Just like you and me, fish need to breathe.#N#To do this, fish draw dissolved oxygen out of the water… 2 Increase water movement More

Why is my aquarium water bubbling?

Bubbling might take place because of a malfunctioning filter, which is definitely not something you want as that will leave you with unclean water, which is inhabitable for fish.

Why does my hanging filter make bubbles?

If the flow of your hanging filter is too high, the filtered water pouring out of it will hit the surface tension of the aquarium water and force a large amount of air under the water surface, which will create multiple bubbles.

Why is my aquarium filter so dirty?

A dirty filter is one that has a lot of protein buildup, including plant matter, uneaten food remnants, fish waste, etc. Water that is high in such protein causes air to stick together and forms multiple bubbles when it comes out of the filtration system. These bubbles then disrupt the surface of your aquarium water.

What are the symptoms of gas bubble disease in fish?

Symptoms of Gas Bubble Disease in Freshwater Fish Bubbles are macroscopically visible within the cornea of the eye. Bubbles within the skin may be visible as an external lump or felt by moving a hand along the fish. Internal bubbles are not visible and may cause tissue degeneration.

Why do fish have lesions on their gills?

Thus, lesions are common in gills, and the choroid gland of the eye. In water that is supersaturated, fish equilibriate with that supersaturated gas, just as human scuba divers equilibriate with gas at high pressures.

Why do gas bubbles cause thrombosis in fish?

As well as impeding blood flow, the gas bubbles can cause pressure necrosis of the vascular endothelium, and subsequent thrombosis. This is commonly seen in the gills.

How does a fish tank air pump work?

You need a way to create the same type of movement in your aquarium. As your fish take in oxygen from the water, they release carbon dioxide. A fish tank air pump creates bubbles that remove undesirable gases from the water. Wands and air stones create streams of bubbles that make your aquarium look pretty, too.

Do I need a bubbler for a 10-gallon tank?

But if you have a 10-gallon tank that has lots of fish, you most likely will need a bubbler. The most extreme clue that your tank is lacking oxygen is that your fish are dying. Fish can die for other reasons, but if you notice the other clues in conjunction to fish dying, you should take immediate action.

Do I need a bubbler for my saltwater aquarium?

Saltwater tanks in particular should have filtration and circulation that beat any bubbler. However, for smaller freshwater setups, an aquarium bubbler can be beneficial. Whether you need a bubbler entirely depends on your setup. Many people use bubblers when creating a DIY equipment such as sponge filters –…

What is a bubbler?

A bubbler is a piece of equipment that generates bubbles that create agitation at the surface of the water when they pop. When the bubbles agitate the water, it allows for oxygen to be dispersed throughout the water.

What is the purpose of a bubbler in an aquarium?

The primary purposes for an aquarium bubbler are: Aerate the water – The oxygen in the tank enters from the surface and dissolves into the water through gas exchange. When the surface is still, less oxygen can enter the water. But when the bubbles from a bubbler rise and agitate the surface, more oxygen can enter the water.

What are the toxins in a fish tank?

The three main biological toxins that occur in a fish tank, which helps in the pollution of a fish tank, are ammonia, nitrite, and nitrate. These three toxins should either be converted or expelled from the fish tank by the means of a “nitrogen cycle”.

How to choose the best water filter for your fish tank?

For large fish tanks that are over 30 gallons, they require filters with more power to clean the dirty water. Hence, external canister filters or wet/dry filters are the best options for this type of tank as they are the most efficient. Before buying a filter, you need to know what type of fish you have or want to have in your fish tank.

Why is there a bubble on the surface of my water?

You see, It can be tricky to determine if the cause of the bubbles on the water surface is from your filter. This is because the filter outlet is generating a current that pushes the air bubbles around your tank. These bubbles will float around until they find a surface to cling to.

What are the symptoms of GBD in fish?

Fish with GBD often exhibit loss of equilibrium, abnormal buoyancy and may float at the water surface. Fish may also exhibit violent head shaking, convulsions, flared opercula, release of excessive gas from buccal cavity, blindness and may die with the mouth open.

What happens if you put a hose in a fish tank?

When the cold water in the aquarium is suddenly heated, it can release and trap gases within the water causing gas bubble disease in the aquarium fish. Similarly, pond or tank water can become supersaturated with gases when they are filled with well water through a submerged hose.
