The slime-coat on a fish is called the mucoproteincoating which is like a longer way of saying mucus coating.
AnswerIt helps them swim easier.The slime coat of fish are the first and best defense against parasitic infections. Parasites such as ich and velvet have trouble attaching to the host fish through the slime coat.
Because when a Algae Eater becomes fully grown it likes to eat the slime coat off the other fish. ( NOT all Algae eaters though) for example the Chinese Algae Eater WILL eat the slime coat off the other fish when it is fully grown.
mucus? Doesn't ring a bell. Fish generally have what is called a "slime coat", which protects them in the same way our body oils protect us.
Of course it's normal. Fish are not toys. They are living creatures who do not like to be picked up and if you insist on doing it you can expect the fish to die fairly soon from stress if not from other infections. Handling a fish damages its protective coating of slime. The next thing that happens after the slime coat is damaged is the fish gets a fungal infection and then it dies.
I believe you mean the fishes mucoprotective slime coat. It is there to protect the fish from things (bugs/chemicals/etc etc) in the water that may damage it.
The slimy coating on fish is a mucus layer produced by their skin. This mucus helps protect them from infections, parasites, and other contaminants in the water. It also reduces friction as they move through the water.
Handling any fish, regardless of where they are from, damages the epidermis and removes the slime coat, which can cause infections and other problems.
Scaled fish have a healthy slippery slime
its protection is the slime on its body
goldfish have a protective slime coat to keep them from getting sick. It's likely that the goldfish find it tasty. If this occurs often, you can buy a slime coat solution that encourages regrowth of it.
no they need slime. if its a slime alien it needs slime. that's why its called a slime alien. but it will grow in jelly too though
All fish have a coating of clear slime to protect them. If your goldfish have brownish slime then the fishes water needs changing urgently.
