How do fish use their swim bladder to float or sink?
If the bladder is filled with gas it will expand slightly and the fish will gain size but loose some relative weight so it will rise in the water. If the opposite happens the bladder shrinks in size therefore the fish has less size for its relative weight and the fish sinks.
Fish's swim bladder affect its overall density by increase the fish's volume, therefor the fish's overall density decreases, it keeps the fish from sinking in water.
By adjusting the amount of gas in the swim bladder, a fish can change its buoyancy allowing it to move up and down in the water column. A submarine can pump water into and out of its ballast tanks to achieve the same effect.
Does the thresher shark have any predators?
- Humans are known predators of sharks most commonly included in the diets of Asian cultures. i.e. shark fin soup.
- There are many types of small sharks that are no doubt part of the diet of other predatory animals in the ocean. Also sharks have been observed eating other sharks. The Sharks predators are Dolphins, other sharks and people! But people are the worst.
- Humans are the worst, but Dolphins will take a full run at a shark and knock the breath out of them with their rostrums(mouth part) and if the the shark is stunned enough and it doesn't breath correctly there are times they will just drift to the bottom of the ocean after a Dolphin attack and die. However, Dolphins will usually only attack if they feel they are threatened, as sharks are predators to Dolphins as well.
- Orca whales are also shark killers. They are the apex predators of the ocean.

How long does a blob fish stay alive?
They are short lived by comparison to a normal goldfish due to the way they have been developed/bred away from the natural shape. A normal goldfish can be expected to live at least 20 years under reasonable conditions. The Bubble eyes, the Moors, Lionheads etc all have much shorter lives of around 10 years.
That depends upon several factors, including:
- Length of time from harvest
- Condition of waters from which it was harvested
- How it was handled after harvest through distribution to consumer
- How the consumer handled it
- What temperature of past and current storage
Freshly caught fish can spoil within one day if left at ambient temperatures. Refrigerated fish could last up to one week. Freezing will prevent bacterial spoilage, but the fish could eventually develop freezer burn or turn rancid.
You have to keep fish on ice. If you fish and leave the guts in and don't have a lot of ice and you get in at late afternoon it will start to turn. But if you gut it and put on ice the fish could last maybe four or five days.

What do you do use if your fish is sick?
Hello, there are a few different treatments than can be used to help a sick fish back to recovery. First you have got to find out if its bacteria, fungus, stress or anything else really. A general medication that covers most is called a 'broad spectrum' medication which is just like a multivitamin and antiseptic for ur fish. Im pretty sure it can also be called multi cure too. Otherwise if u have a fungal issue u can get medications just for that. Basically after treating ur fish for the recommened time you will have to give ur tank or bowl a waterchange to resore the water to its normal state, and dont mix medications unless u are advised too. So the best bet would be to go into ur local aquarium and explain the symptoms and they will be able to point u in the right direction. I hope this helps :oD
What would happen to the small fish population when there are less big predator fish?
The population would explode, becoming overabundant. Eventually, all the food would become exhausted and the fish would starve.
That's why it's important to have a balanced amount of predators and prey.
Of course, there should always be less predators than prey. The problem arises when there are less big predator fish than there should be.
