Your betta may be suffering due to bad water quality when it has not been changed enough. You should make sure that you change some, or all of the water in your fish tank at minimum once per week, or more if it's too small.
It may be possible to save your fish provided you keep the water extra clean, and add some aquarium salt (1 tablespoon per 5 gallons of water), and the correct dosage of Melafix per the instructions on the bottle. Do not use regular table salt, this must be aquarium salt or epsom salt only.
NO!!!!! They should not eat betta fish...but if your cat has then call a vet, and don't get anymore betta Fish!
betta are not harmful to people and most tropical fish. However, there are some very common fish that are poisonous. Most of the common plecos with spines can be toxic to tropical fish if they are dumb enough to peck at it. If you feel that another fish you own will get sick from being around your betta, odds are the two can live together happily and healthily. If another pet, like a cat or dog swallowed your betta, I wouldn't worry. I have never heard of pet poisoning from eating tropicals.
Coming in contact with human skin will not kill a betta. However, bettas are very fragile fish, so care should be taken not to handle them for fear of damaging their internal organs, fins, or scales.
A betta fish laying sideways may be a sign of swim bladder disorder, which can be caused by overfeeding, poor water quality, or stress. To help your fish, try fasting it for a day or two, then feeding it a pea without the skin. Ensure the water is clean and at the right temperature, and consider adding aquarium salt. If the issue persists, consult a veterinarian or a fish expert for further advice.
A Betta anatomically is basically the same as any other fish differing only in its having an extra method of getting oxygen into its blood stream. It has a thing called a Labyrinth in its skull. This is like a chamber with very thin wrinkled up skin that has millions of tiny blood vessels in it. When the Betta takes a gulp of air, it goes into this chamber where gasses are exchanged in a similar way to what happens in our lungs.
It is a skin fish. The skin is very soft and free of scale.
In Indonesia, Cupang has two meaning: 1. Betta Fish 2. Sucking neck or breast of other gender with our lips until produces red color on the skin surface of the victim.
Betta fish can communicate through colors and body language. A betta fish can use fins to show it is ready to breed, and can change its skin to have black or dark vertical bars to show it is ready to breed. A male can communicate to other males to stay away by flaring it's fins and fanning it's gills at it's intruder.
It depends on what kind of skin you have. If you have sensitive skin, then yes, fish oil can penetrate your skin.
No: fish have scales, not skin, unlike reptiles which have scaly skin (there is a difference).
A fish has scales
Fish do not have human skin except in the movies or science fiction books.
